Blacklisted people no longer being blacklisted be like:



...but in all seriousness, you can't simply stop being blacklisted in a trivial, easy-to-toggle fashion.

I mean, you can go out of your way to make alts or attempt to invalidate the blacklist handle. (There have been reports in the past of people paying to world hop to another DC and then hop back and having their blacklist status reset.)
However, at that point, it's the same thing as paying your ISP for a replace-on-demand IP and having tons of email addresses in order to bypass forum bans. You're giving yourself extra work, and they still won't listen to you.
