I am trying to get rid of a spammer twitter (pigeonpoll) for about four days. Look at the following image. That is what happens. I say I do not want to follow it anymore, and twitter says, ok, you are not following pigeonpoll anymore, but you are still following it. Just because I got enough of these stupid polls, I tried to block pigeonpoll. Unfortunately I am still getting messages from it.
The truth is that it was my fault, as I had enabled twitter API to pigeonPOLL. In any case, pigeonPOLL should respect my decision at twitter, and twitter should give a warning message instead of the stupid screen shown.
