Just a note to let mark_up and chevas know that they've been hellbanned. I don't think you're trolls, so I thought I'd let you know (I can't respond to your posts directly).
mark_up and chevas: Looking at your comments history, it doesn't look like you post inappropriate comments, and have most likely been banned by mistake.
You can make new accounts, but I would suggest getting your current accounts unbanned. A short mail to pg(you can guess the email address) on the lines of "I believe my hn handle http://news.ycombinator.com/user?id=mark_up is wrongfully banned" does the trick.
