Jenny, Lately the spam we've been receiving is a lot like some spam emails I receive which are not actually generated by a person (though it does take a person to sit doen and write the software that makes these "spam-bots" run). I suspect at some point we may have to consider adding a feature to our login that requires a human response, but that's a thought for the future.
In the mean time keep reporting the spamming everyone. We've grown to the point where its impossible for an administrator or moderator to read every single post in every single thread....though I think sometimes Fred comes close to doing that.
We appreciate your reports!
