Can Riot add a block feature for the boards to get rid of those pesky post stalkers?

If you feel someone is harassing you, please use the report button on the right. Moderation will handle it appropriately according to the boards rules.

so who the hell did you piss off to get post stalkers?!

Using F.E.K, it is possible to block that said person.

Go into the General Discussion board's sticky and you should be able to find it.
