In order for your theory to be valid, 2 external sites need to share the IP database and create a compare analysis tool in order to decide whether or not to ban you. But that already defeats the purpose if most people already visit popular social networks all day. No reason to hide facebook or twitter links behind short urls.... also there's no point in hiding unknown websites behind shorturl's in order to harvest IP's, since you would probably visit those sites once in a lifetime, and like i said in the beggining, it would only be effective if they shared IP database with another website (which you will barely visit to begin with) and they will decide whether or not to ban you. But ban you from what? It's irrelevant. Your assumption is not smart and it's pretty dumb in my opinion.
What you're basically saying is not really what OP is saying, in that "be careful of the shorturl's because they capture your IP's".... capturing your IP's doesnt do anything if every website already does it automatically on the server side.
I don't think you know how the internet really works, or how smart criminals would use these tools to their advantage.
