I would like to delete my account (which I know how to do) but also all my made comments.

I've seen the "delete account" option, so that is not a problem.

But I would like to delete all my comments as well. I made a total of 89 comments and deleting them one by one should be quite a task as every request to delete a comment is to be reviewed by an admin.

Is there a way to get a hold of an admin and request a complete deletion?
