I can change your username and ban you, which could help disconnect the account from you. I don't have the ability to delete all posts an account has made, and there's an unfortunate glitch with posts that old that make editing not work. That's a relic from the Guild pre-update and a bit of a perfect storm in this case.

Like I said, I would be more than glad to delete any specific posts you'd like removed.
