:: Blacklists or Bayesian filters are not very effective ways to filter spam, and they create false positives. A good spam filtering is based on what the spammers are actually selling: their contact information (e-mail address, web address etc.). I would think there is only one or just a few spammers that bother to manually create pages here in Rosetta Code, so it should be possible to add their contact information to spam filter manually. --[[User:PauliKL|PauliKL]] 09:59, 2 July 2009 (UTC)
::: You could also try simply turning off the creation of new accounts for a while (e.g., a couple of weeks) to encourage the spammers to go elsewhere. The number of new genuine users turned off by this is probably going to be quite small, and the problem does at least seem to be confined to user pages. —[[User:Dkf|Donal Fellows]] 13:23, 2 July 2009 (UTC)
:::: They're still using identifiable names that could be caught by RE like "[0-9]+\s*buy"; if stopped this way, they can for sure change approach, but if they are landing-pages, likely the username must follow a pattern an airplain can identify, and then they must change their OLS signals, so I believe it is not a so bad approach to fight them. I like the idea of silent failure and honeypot page, even though I've not the slightest idea on how it could be done on mediawiki. --[[User:ShinTakezou|ShinTakezou]] 13:42, 2 July 2009 (UTC)
