mollom growing pains?

so far, mollom is only blocking about 90% of spam attempts. which would be fine, except I've already had 219 spam comment attempts in the few hours since enabling mollom - so over 20 spam comments have snuck through to get published. that's almost forgivable as a fact of online life, and maybe growing pains in mollom itself - but apparently there are false positives as well. that's just unforgivable. and mollom nukes anything it thinks is spammy, so there's no recovery or second chances... not sure if mollom will survive the full week test run...
