What the system thinks is spamming will stop you from commenting.

There was a stretch of bout a year where I didn't comment on anything. After that time, I commented on a game, and boom, every comment I have tried to post on a game page for the past months has gotten filtered away. Everything I previously commented and have been trying to comment has been legitimate comments and not commenting too fast, yet the system keeps me locked up in Waiting On Mod Approval and support won't do a thing about it.
