I honestly regret making an account and idk why I really thought it was a good idea. It’s not like I’m really doing anything with it. If there isn’t a way to delete your account and the most you can do is permanently ban me, then I’ll take that.
If you feel really strongly about having your account deleted, I suppose you could appeal to an administrator to see if one of them will. Experience tells me the staff and admins don't want to do things that would upset the site's history without good reason, but they might be willing to help you with such a low post-count. Ask one of them via PM.
I'm not sure if it entirely matters with you having only 3 posts, but it's your call.
