I get it, a lot of us like to get HEATED sometimes, myself definitely included. You should go through periodically and unblock other Hexbears though unless you still remember why you blocked them and are still mad about it, or if you think they're actively harming you with their posts (in which case you should report them so they get banned).
Give folks chances to learn and grow once you've cooled off and once they have cooled off and try the unblock function once in a while.
Just a PSA to help keep the community a community; we're too small to be blocking each other permanently all the time. Blocks are useful for sure, I've got a few folks blocked myself, but once everyone has cooled off and the fight is a distant memory, give the unblock feature a try too.
We are not too small to be blocking people. In fact, I'd say we're too small to NOT be blocking people because you will run into them like every week. And the toxicity of disliking someone and not staying away from them is also Very Bad for community vibes.
Lastly, you should be making a new account and leaving your old one behind at least once a year for opsec reasons. This will reset your block list unless you take the time to recreate it on the new account.
