Just a reminder about peak wiki,
adding content is more fun then removing spam.
A few options to consider...
$this->bbcode_second_pass_quote('', '[')b]ConfirmEdit
Install the ConfirmEdit extension. ConfirmEdit uses captchas (simple
tests to "prove" an editor is human before registering an account or
allowing certain types of edits) to prevent many spam robots from
inserting spam into a wiki.
You can use "fancy" image captchas with squiggly letters, the kind
everyone is used to seeing these days, or you can opt to use
simple math problems. The image-based captchas present problems
for blind people, but it's probably easier to write a spam robot to
detect and do math problems, so there's a tradeoff. I use the math
problems on UMassWiki for maximum accessibility. They're very
simple addition and subtraction only.
