As you have noticed we occationally get someone who joins the site and thens sends out a message about junk. As soon as Jerry or I see it we remove them and the message although by that time it has already gone out to all of you. This is the third time for this particular person. I banned them from the site but they will be back again under another user name.
We can set this site up so we have to approve membership prior to it being official. In other words someone will apply as you all did but instead of it being automatic the site emails Jerry and I telling us to decide if this application is ok. If it is we click ok and they are good to go. If it isn't we click refuse and they go away.
So far we have only had about 4 occurances with spammer on this site so I am not to worried about it now. If it starts to increase then we might consider the above.
