Re: [Phpwiki-talk] Wiki spam and the future of phpwiki

[Mario S. <ma...@er...>]

Hey Philiph,

I can't comment much on PhpWiki development, but I doubt that any
eventual bugs couldn't be fixed. As for PmWiki, I think you're trading
something robust for spaghetti code and one of the more weird Wiki
markups around, if you'd really switch.

Link spam is a problem that escalated only this year, so it's clear
that we all first need to find "THE solution" to it. IP blocking and
whatnot blacklist however seem to be more hassle than they help
here.
I had best results with blocking posts that contained more than a fixed
number of new links. AFAIK there is already such a plugin for PhpWiki,
so you should give that a try. (it's called "LimitExternalLinks" elsewhere)

I've lately completed a CAPTCHA, which is extremely easy to integrate
even if you don't have years of PHP experience.

While allowing you to keep your Wiki open, it's still a bit anti-Wiki to
use captchas; but as last resort I would recommend it.

Most link spam hits the Wikis only accidentially, and was originally
targetted at BBcode- or HTML-enabled blog/comment sections. You'll
need something that blocks any "/^<a.+</a>$/" edit form submissions
then (also easy to do).

In your case (500 edits) it however sounds like you've been attacked
targetedly - in such cases no anti-spam plugin will help you and
cleaning up the mess afterwards is the only solution. If you're using a
SQL database - that's often forgotten - then it's a snap to wipe hundreds
of pages at once, depending on a timestamp.
Else you only need the right tools - the funny WikiCommander and the
"mass revert" tools in the Wiki I'm working on would do. (I'm link spamming
here ;)

Our database API is extremely simplistic, and so writing up some glue
code for PhpWikis should be trivial (right now we only have a PW plugin
without ::DELETE support).

Whatever, I just wanted to comment that this is not a problem
only PhpWiki faces, and people all around are testing and writing
tools to combat link spam. And simple solutions surprisingly seem
to work best.
