Bug in URL spam filter

Arne 'Timwi' Heizmann

Today I added a table with some figures to the article [[Cocoa]]. Here's
the edit:

http://en.wikipedia.org/w/index.php?title=Cocoa&diff=167748653&oldid=167579349

Note how I added a URL to back up the numbers.

It allowed me to make one more edit to the same section. After that, I
couldn't edit the section anymore. Supposedly the URL that I just added
is in the Spam blacklist. That is quite ridiculous seeing as I only just
added it and it was accepted.

I had to REMOVE A REFERENCE in order to SAVE AN EDIT. I think this is a
rather severe problem because it means that users will be prevented
(even more than they already are) either from providing sources or from
editing out errors.

The fact that it's a bug is further demonstrated by the fact that after
I removed the URL with my next edit, it suddenly allowed me to add it
straight back in. It should not have been necessary to remove it.

"suite101\.com" has been on the blacklist since November 2006:
<http://meta.wikimedia.org/wiki/Spam_blacklist?diff=472751>. When I
tried to create a new page containing your link, the spam blacklist
correctly caught it. It sounds like the spam blacklist is (or was)
being enforced sporadically.

Yours cordially,
Jesse Martin (Pathoschild)

Should the spam blacklist even apply to established users? Twould be nice if
we had a way of marking generally trustworthy, reliable users...

It probably should. Since this list is used by many MediaWiki
installations, not just by Wikipedia, it should only be for sites that
are really spam which should never be included in any wiki, not just
for sites which are ok if linked to by admins.

Incidentally, what happens if a site is notable as a source of spam? Is it
really impossible to link even once to them? I've never seen this spam
filter in action...

The problem here is that new users or anonymous editors would not be
able to edit the section that the link is in, otherwise they would
trigger the spam filter and would not be able to save their edit
(without removing the link, of course). Since the current system for
comparing edits is unreliable such a feature where by if users don't
*add* the link it saves would be very difficult to create - maybe once
blame functionality arives we will be able to do that.

Well, given what Angela said:

clearly the rule "suite101\.com" urgently needs removing. Also, perhaps
  User:Mzlla (who added it) needs a bit of a smacking :-).

Indeed, I thought the feature was added to give us a technological
edge over bot-net spammers (or other situations where individually
blocking IP addresses isn't effective enough).
