if you use existing unflexible anti spam tools(spam assasin and such) then
if you use flexible tools like bayesian filters or hand written scripts
then no
just think about it, 1 spam filter everyone is using, its trivial for the
spammers to adapt, but they wont adapt to a simple script which is specific
to multimediawiki
or to look at it at a larger scale, there are few spammers and many many
more non spammers using the sites, if every site would use their own
unique spam filtering system the spammers could never adapt to it ...

see, thats exactly what i meant :)
the spammers dont have and never will have tools which are specialized
to each site, a few simple changes and they are left to manual spamming
which you wont prevent with CAPCHAs, subscriber only checks or even
"contact me and ill create an account ..."
