Ever wonder how to get rid of the spammers on Twitter? TwitBlock is a great way to find the ones that have followed you and whether or not they could be the same spammers.
Using a special algorithm, it calculates out whether or not a person is potentially a spammer and gives them a score. Based on whether or not TwitBlock users have marked the user as a spammer, the effect of the scoring goes up or down. It’s actually a pretty interesting method since most of the ways of detection are common sense things.
I would probably say that most people that have more than a thousand followers probably have quite a few bots and such on there, but at least there’s a way to somewhat detect these now instead of going through your followers one by one.
If you’re curious about it, definitely run this every so often on your account. It uses OAUTH so you actually never give it your password and such which is a great thing from a security standpoint of a third party application. Give it a whirl.
