Joseph, well I'm not Mark, I don't think there's much he can do. Except mandate everybody to approve their subscribers. And/or have their message limits set to whatever. I know it makes more work for the individual owners and co-owners and moderators, but it may be what we have to do.

Subject: [GMF] Spammer attacking multiple groups
The user abnersadik96@ GMAIL.COM has been joining groups with a reasonable first post, then spamming the group promoting their sale of masks.
If you see a notice that they have joined your group you might want to ban them. At the least keep them moderated after their first post.
[Mod Note: The same spammer tried to do this in GMF, too. He has been joining multiple groups using different gmail addresses.]
