Last year, @BruceJillis and I created Gunfollow. Recently, there seems to be a renewed interest in this Twitter hitman of sorts. So we’ve been thinking of ways to make Gunfollow even more fun. The easiest way to do that seems to be to add more messages. Gunfollow uses a predefined set of “semi-rude” tweets that it sends to its victims. But not all of them are as witty as we’de like them to be. And that’s where you could come in .

The Twitter community has a very positive feel to it. This is in part because unfollowing other users is easy, and unless the people being unfollowed have special tools in place, they’ll never know.

But sometimes, simply unfollowing someone is just not enough. That’s why there’s now Gunfollow.com, the Twitter hitman. You can “hire” Gunfollow to unfollow and block a user. It’ll be quick an painless, and you can choose a message that gets delivered to the “victim”. If you prefer, this message can be delivered anonymously.
