Yep I do this all the time when a new member tries to join RPG Haven. Most of the time they're a spam account so I immediately ban and delete their account.
Yes, because I want to ensure my members are unique, especially in poker, where money is involved, and to maintain a safe and secure environment for all players.
I used to do this all the time when I was fully invested in the forum world. I knew every person's pattern of speech, preferred VPN's and actual IP addresses.
I’ve started scanning new members too, but I focus a lot more on the username and email than the IP itself. The biggest red flags for me are things like dropping links in the “About” section without ever posting, mismatched usernames/emails, or profiles that look auto‑generated. Those patterns tell me far more than an IP ever will.
For IPs, I generally don’t take action unless the account is actually posting spam. I almost never IP‑ban someone just for registering. Before I ban an IP, I’ll usually check whether it’s a VPN, hosting provider, or Tor exit node, especially if the account is throwing a bunch of red flags but is acting somewhat legit. That helps me avoid banning someone who might just be privacy‑conscious.
So, for me, it’s more about the overall behavior and signals rather than treating the IP as the deciding factor. The IP is just one piece of the puzzle, not the whole picture.
