I won't reply to your PM as I can post here directly. This case is better suited for a moderator action that wipes all those accounts IMO[1]. However, I'll take a look myself when I find some time.
[1] I had a similar case where 40-50 accounts (all jr. members) enrolled themselves within 30-60 minutes. Talk about being obvious.
Hi, Lauda, is there a way to increase the rank requirement for joining any campaigns. It is obvious that some participants are abusing the campaigns, you can see a lot of junior members spamming registration and even cheating registration in signature campaigns and other campaigns. I think if possible, let only those who have merit or Member rank join any campaigns.
