Hi, I hope this is the right place to post this. :) As an owner of
several Yahoo Groups, I'm completely tired of having to moderate my
groups, only to find that despite being fully moderated, spammers
inevitably sign up for my groups and attempt to spam anyway. I've now
resorted to restricting memberships in addition to fully moderating my
groups.

I've created an informational blog about this. My blog contains a
message which can be sent to banned spammers, a home page notice for
group owners who decide to restrict memberships, plus a (no doubt
partial) list of spammer names which follow a certain pattern.

Here is a link to my blog:

[Mod note: I am not sure such extreme measures are necessary.]
