Yes, it is possible.

There are plug-ins like Bad Behavior, which detect spammer by their behavior
and disable access for them. Unfortunately, Bad Behavior didn't catch many
spammers on the Wikis which I administer. Instead, it managed to lock >>me<<
out. Me. The Wiki admin!

I now use some regular expressions, which the Wiki software (I use
MediaWiki, just like Wikipedia) applies to each edit, and refuses to save
the stuff it the regexp matches. Works surprisingly good. And anything which
gets through (both spam and ordinary vanadlism) gets cleaned up the users
which happen to stumble upon such an "re-decorated" article.

Best regards, Klaus
