Digg has a harassment problem.

This is just a small selection of the posts made on my community by one user (whose previous account also made a half a dozen such posts). Because one person has become obsessed with a perceived personal slight (I removed an off-topic comment they made on a thread), they have turned the entire community into a monument to their obsession.

There are no tools available to me to remove these posts (they blocked me, so even as the community founder I cannot remove their posts) or prevent this user from making them in the first place. Even if there were, they would simply make another account and continue.

Their first account was deleted by the admins, but they started this one shortly after and it has been active for the rest of the day. There have been over 40 similar comments or posts made by this user directed towards me in a 12 hour period.

How can I recommend this website if small communities can be rendered unusable by a single troll?
