Spam bot invasion
I have scanned through 'all pages' and deleted all spampages there, luckily easy to recognize due to loooong page names. Afaik no more spam is present, just some contributions from the Active user list that I can't locate anywhere.
Those buggers are smart. They create an account and then spam from it after some time passes. This is exactly what GrubbmGait predicted above.
We just need to embrace ourself for couple weeks. I suggest to put
[[Category:Spam]]
text within the offending pages so admins have easier time to track them down.
Yes it helps. Anyway, the best way against human spammers is that we have more people than them;) At least with more admins it really helps.
MultiplyByZer0 sees the wiki very frequently, we would react to spammers much faster if he were admin as well;)
Well, we just need to be patient. As much as I hate spammers, wiki will run even with spam inside. Wiki is not the twitter where everything should be immediately up-to-date.
I personally monitor Recent changes in my rss reader, so I see the invasion within couple hours. But we cannot expect admin reaction time to be much faster than a day or even week.
This is not the first spam wave (though the largest I remember) which we survived.
