Spam filter too aggressive

[Janne Jalkanen]

Hi folks!

It seems that the current spam filter has some bugs.  It's blocking  
too many legit edits, and it's blocking even spam which it is not  
supposed to.  I think there are some genuine bugs in it - but on the  
other hand, considering that we get about 200 spams/day, it's working  
great to keep those out.

However, some strategy improvements are needed.  Please throw some  
ideas here (and consider that spammers are intelligent, and can learn  
to register automatically).

I think the solution is to create a trusted characteristic for selected
registered users.  Herb watches for suspicious activity from
non-registered users and users without the trust parameter set.  Now the
trick is how to set the trust parameter, preferably automatically.  
Someone else suggested that this might be set by a number of successful
edits.  I think that's reasonable, perhaps augmented manually for
specific cases.  Maybe trust (however determined) could be implemented
via group membership, to use an existing mechanism.  The mechanism for
identifying when to grant trust and to whom could evolve over time -
just having the method available to bypass Herb under certain conditions
would be a good move, IMHO.

I'd have to agree with Terry -- there kinda needs to be Yet Another
Category of user, one that is *manually* determined by the wiki
administrator. I'm planning to put up my own wiki fairly soon and
will likely only (at least at first) grant edit rights to specific
individuals by invitation. I simply don't have the time to deal
with spam right now. But at the point when I'd open up the wiki to
permit registration of strangers, I'd like to then have some way of
determining a trust level, which could be a feed (an a numeric value)
right into the spam filter, so the higher the level of trust the
less likely the spam filter would trigger. After a certain number
of edits the user would have the equivalent of "full trust" and
the spam filter would never get set off.
