I’ve been dealing with an increasing number of spammers/vandals defacing pages on TinyScreenfulsWiki.
It used to be an infrequent problem, and not a big deal for me to roll back their changes (usually a big block of links to sites selling prescription drugs, etc.) and ban the user. I’ve got MediaWiki set up to require an account to make any changes to the wiki, but anyone can create an account. I hestated to lock it down any tighter, because I use that wiki to teach people about wikis in general, and I didn’t want to make it too inaccessible.
In the last week or so, though, it’s been more common. I don’t know what the spammers think they’re getting by vandalizing my wiki – I usually roll the changes back within a few hours. It’s a person creating the account and making the changes, or at least, I don’t think it’s automated.
Anyone else dealing with wiki defacement or spam? Know any good ways to deter them? I can think of some ways that involve a baseball bat and kneecaps… }:-/
