I sent a report asking what I did wrong, this was the response:
"Hi! We recently made a small change to how our IP bans are processed, and s small bug turned up which resulted in many people showing as banned from posting.
You didn't do anything wrong (or maybe you did, we don't judge)! But we are sorry for the inconvenience. The problem should be resolved as of now, and you can resume your regular forum posting habits!
Thanks again for the notice, and have a great day!
Regards,
Louis (ThyNameIsMud) Weber"
Just hope that clears up everything.
If posting report replies are a bannable offence, I'm really sorry for not knowing.
