The Block Bot application is an abuse of the Twitter API's block function to implement a shared block list - anybody who authorises this app gives it power to block hundreds of twitter users who have been added to its list for no good reason. The developer claims it is to block trolls/abusers but, in reality, the members of the list can be added for a variety of reasons - even as simple as disagreeing with somebody the developer, or his friends, don't like.

In this sense, the app's purpose is entirely misrepresented. People added to the list by this arbitrary criteria will then be blocked by anybody who authorises the app.

This has also resulted in mass spam-flagging on certain accounts, triggering the automatic suspension system.

Many good people are being blocked by the users of this application, simply because their name was added to it by one person. This is not in keeping with the spirit of twitter.

The app essentially gives power to specific individuals, to add names to it and have all of it's users block that person (without the app users even knowing).
