      Wenn man gefiltertes Internet kriegt, ohne gefiltertes Internet  
zu wollen, ist es Zeit, sich zu wehren. Das haben 25  
Gruppen - darunter quintessenz und VIBE aus AT - der  
Global Internet Liberty Campaign einmal getan.

A group of 25 Internet civil liberties organizations, including  
the American Civil Liberties Union, the Electronic Frontier  
Foundation, and other members of GILC.org and IFEA.net,  
released a co-signed statement today against the practice of  
Internet Service Provider "stealth blocking".  We first posted  
to our press list about this back in December, when we found  
out that AboveNet, a large backbone provider that apparently  
routes about 2% of hits on any given Web site, was blocking  
their downstream customers from viewing the Peacefire site.   
TeleGlobe, a backbone provider that links many European  
ISP's to the American Internet infrastructure, is also still  
blocking their downstream users from viewing  
http://www.peacefire.org/. 
 
Of course, we're already blocked by all the major blocking  
programs, since the top link on our site is "How to disable  
your blocking software".  The twist was that in this case, the  
customers downstream from AboveNet and TeleGlobe didn't  
sign up for "filtered Internet access" -- the vast majority  
thought they were getting full access to the Internet, and  
when they tried to view our site, the browser would just give  
an error saying "site not responding", even though it was  
actually AboveNet or TeleGlobe blocking it.  Ironically, it  
turned out that AboveNet and TeleGlobe weren't even  
targeting us, but were participating in a boycott of our ISP  
organized by an "anti-spam" group called the Mail Abuse  
Prevention System (MAPS), which targeted our ISP because  
of the content of some other sites hosted there.  (It *was* an  
issue of content -- mostly sites like ListSorcerer.com selling  
email software that MAPS believed could be abused by  
spammers -- it was not because any site hosted by our ISP  
was spamming or being advertised in spam.) 
 
Slashdot ran a story last December about the AboveNet  
situation, and AboveNet immediately stopped almost all  
blocking of Web sites (not entirely -- AboveNet still blocks  
their users from viewing http://www.orbs.org/, which is  
explained rather bluntly on the ORBS site at  
http://lookup.orbs.org/hallofshame.html).  But the TeleGlobe  
blocking is still in effect.  We're starting to hear from more  
and more European users who realize that our site is not  
down and that TeleGlobe is actually blocking it.

The undersigned members of the Global Internet Liberty  
Campaign (GILC) and the Internet Free Expression Alliance  
(IFEA), in keeping with the principle that end users should  
decide what to view and with whom to communicate, object  
to the practice of Internet Service Provider "stealth blocking."  
This concerns ISPs that do not bill themselves as filtered  
service providers but intentionally block their customers from  
accessing certain Web sites or sending mail to users at  
certain other ISPs. "Stealth" blocking is done undetectably,  
so users only see a browser error saying that a Web site is  
down or an email error saying that the destination mail server  
could not be reached.  Over 99% of end users never discover  
that any intentional blocking is being done. 
 
IFEA.net and GILC.org have both fallen victim to "stealth  
blocking" by their upstream provider, AboveNet, which  
blocked IFEA and GILC from sending mail to one of their  
member organizations between August and December 2000.   
During that period, AboveNet's downstream users were also  
blocked from viewing that member organization's Web site.   
The member group's hosting provider was blocked after  
becoming the target of a boycott by AboveNet and several  
other providers, due to the content and ownership of other,  
unrelated sites hosted by the same provider.  After this  
practice was discovered and publicized in December, and  
users confirmed it was not a hoax, AboveNet abruptly halted  
almost all "stealth blocking" being done on its systems but  
did not issue any statement on the issue or say whether the  
practice would be reinstated. 
 
The undersigned IFEA and GILC members are requesting a  
written clarification from AboveNet as to their policy of  
blocking customers from accessing Web sites based on their  
content.  The members urge AboveNet to commit to not  
reinstate their "stealth blocking" policy in the future. 
 
"Stealth blocking" is defined by several characteristics: 
 
- The vast majority of the ISP's end users are not aware of  
any blocking being done. 
 
- Even the ISP's own sales and technical support staff are  
usually not aware of the blocking practices, and, as the main  
point of contact for users, tell them that no blocking is taking  
place. 
 
- The blocking is done undetectably, creating the impression  
that the target Web site or the destination mail server is  
simply not up and running. 
 
This would not include, for example, ISPs that cater to  
conservative families by advertising a filtered service, or any  
type of opt-in filtering system that is selected or installed by  
the end user.  An ISP blocking an incoming flood of actual  
spam or any other type of denial-of-service attack as  
necessary to protect its network would also, of course, not  
be included under "stealth blocking." 
 
The most common reason for true stealth blocking is to  
boycott certain hosting providers that host content that the  
boycott organizers believe is contributing to the problem of  
unsolicited bulk email (UBE), or "spam." This can even  
include hosting providers that refuse to host "spammers" if  
the provider provides hosting to companies that offer software  
or consulting services that are legal but can be used by  
"spammers." An ISP can use stealth blocking to strengthen  
the boycott against one of these providers, by blocking its  
own users from viewing all sites hosted by that provider while  
avoiding outrage from its own users by hiding the fact that  
any blocking is taking place. 
 
The situation provides a valuable test of principle, since many  
GILC and IFEA members and other groups are committed to  
the cause of fighting unsolicited commercial email.  However,  
we defend the right of end users to decide what content to  
view, whether the content is offensive to others, whether the  
content is published by companies that have sold products to  
third-party unethical marketers (spammers), or whether that  
content is controversial for any other reason.  It is not the  
function of ISPs to act in loco parentis for users.  Boycotts  
by individual, informed consumers are an admirable means of  
achieving a goal, but "stealth blocking" by ISPs is never  
justified, regardless of any noble purpose, since by its  
"stealth" nature it violates the principle of end user informed  
choice. 
 
Constitutional guarantees of free speech in various countries  
are not the only safeguards against involuntary censorship.   
Truth-in-advertising also serves to protect users, and  
individuals who do not sign up for "filtered Internet service"  
expect that their ISP will not block their Web access or  
outgoing mail.  If the ISP has not ensured that end users are  
aware of any blocking that is taking place, then the users'  
participation in the blocking cannot be called "voluntary." 
 
We believe that ISPs that practice "stealth blocking" are  
violating consumer protection principles and restricting user  
choice and freedom in cyberspace.
