This is free skeet. Cracks like this are usually built from a memory dump, so they carry a lot of what the real cheat had loaded, including standard gamesense script libraries. polib is one of them and this is helper that sends Pushover phone notifications. Important things is that, there are no calls for this code, no other library that would load it, and there are no Pushover keys in the file in question. It sits there unused unless you load a script that uses it with your own Pushover account, in summary this is normal, and also this free is a bit old, thus a lot of people would complain here regarding stolen accounts, while there are no such replays.
