I was ashamed of myself when I read back my posts under a different alias. Thank god the old Forums got deleted. At least now I'm a better person and have matured a bit since then but I agree that seeing the old comments I've made have really made me cringe very hard. I usually think, "wow, I was an asshole and very petty over trivial shit." Now my perception is different and have better grasp over most of my actions, still need to work on my aggression and anxiety episodes. There are times where I feel I want to post something but then remembered how I was reading my old comments and realize: I don't wanna go back to being that guy again. So I delete those comments and posts.
I believe those old comments serve as a reminder that there is a consequence for our actions. Good and Bad. So in essence, they should stay as they are to keep ourselves in check. You never know when those posts will come back to bite you in the ass. Lest we forget, the rules have changed since the old forums, some things carry more punishment to prevent such kinds of old comments and habits from returning to the new forums. I can appreciate that.
I'm not nostalgic, but I do think we're better people from before we made those comments.
