I have made some changes. I have tightened the spam filters and added to the spam words that could be causing some of this.
I have now gone in and reduced the number of posts that are spam checked, and the days you are a member that are spam checked. Now I'll see if I've tweaked things enough.
And the contact us was getting at least a few spammers each day 3 times a day. So I'm tweaking things.
