This board has been relatively immune from spammers until recently. The latest ploy seems to be to register a name, then post a comment in a topic while hanging out a signature that points to some commercial web site. The comments are generally one sentence and superficial, with misspelled words. They contribute nothing to the discussions, and when members have tried to engage, there has been no response.
So, as of today, I will disable signatures for everyone. Only a few legitimate forum members use them, so I apologize to those of you who do and will miss that feature.
For now, I will continue to allow open registration, but my next step will be to place all member requests in an approval queue, pending my approval. I will also be deleting posts and memberships that have been spammish.
We've had a quality board up to now and I'd like to keep it that way. Questions and comments on this topic are welcomed.
