My IP has been blocked

From Barbelith

Sometimes you'll get a message on Barbelith that says that your IP address has been blocked. This is mostly because of problems with a couple of ISPs that we don't really want to go into too much detail about. If you send Tom a private message it's possible that he can unblock your IP, or at least give you back door access to the site. But this is a privilege NOT a right - these IPs have been blocked for a reason, and if you turn out to be one of those reasons then these back doors will be rescinded site-wide...
