So, I'm the admin for like 5 different google groups. I've set the groups to moderation for new members and membership has to be approved. Still, still, we are getting hit with spam. Finally, as a desperate last measure, I've closed the list down for reading, unless you are logged in. I kind of wanted to keep the list open for reading, but oh well...I discovered that google groups is being hit with spam and there has even been some chatter on the 'net that google is slowly dumping google groups. I don't know that to be true, but there's the 'net gossip and the Jquery list dumped google groups back in October.http://www.webmonkey.com/blog/Google_Groups_Fail:_JQuery_Dumps_Google_Over_Spam__Interface_Problems
