Yeah, I’ve dropped the TL1 requirements slightly from the defaults due to user griping, but it’s still been enough to keep actual spam posts off the forum. It’s a really great system, IMO.
Here’s a screenshot of a few representative spammers:
I believe they’ve been confirmed since there’s no way for them to fill out the profile with their spam website until that point (AFAIK). It’s not a huge deal now that I know how to not fill up my moderation queue with notifications, but if they ever get smarter/more persistent, I’ll have a problem lol.
Anyway, let me know if there’s any more info you would like me to gather.
