I have a board that has historically been open to anonymous postings. In the last couple of days I have had several hundred postings for online poker sites. These all are coming from different IP addresses (probably faked). Anyone have a suggestion for stopping this besides removing Guest access to post? Also, when I remove Guest access to post, the "post" and "reply" links go away (as they should) but I suspect I will get a lot of people asking how to post. Any way to leave those buttons on and tell people they need to register to post?

Thanks

T
