here is another gift to you. A free twitter Adder/Removal Software .
Twitter Application was made using with UBOT to make adding targeted followers on Twitter a breeze. You can add by keyword, username and can easily harvest a couple of hundred users a run. (Depending on your keywords). I have found the software to be extremely effective and unlike a lot of other Twitter Adders out there it uses the web to add and remove users. It appears to Twitter like a real user is adding followers as new users are added at random intervals.
