I run a free browser game where you can start playing immediately, no registration required. The game has a big sandbox element where you can build and paint on the world map.
Naturally I've attracted trolls doing everything in their power to grief and ruin it for other players. This has lead me to reluctantly implement moderation tools such as IP bans and proxy detection.
I'm currently using a couple of services where I can supply an IP and get a risk score back but I'm worried about false positives. I'm afraid this initiative, while great for privacy, will make my defense measures futile.
What should I do? I just want to run a game with as few intrusive barriers as possible. I have no interest in collecting any private data from users whatsoever.
