[wp-hackers] An idea for preventing spam

[David Chait]

I'd agree it doesn't warrant its own plugin just for that one case. 
CG-Antispam uses a number of techniques, including looking at the links in 
the comment versus domain/word blacklist, number of links, repetitive posts, 
etc.  There's more to it than just something that simple -- you just happen 
to have hit a single-patterned spammer at the moment. ;)

But there's a half-dozen antispam plugins out there that should catch it 
already so long as it's hitting one of the existing filters.  A few do let 
you add your own regex (I don't currently, as I try to avoid regex tests for 
speed reasons...), if you find stuff getting through.
