go to the profile at the top of the page, hit it and it will show your rep, green dots are good, red ones bad, you get rep points for the good rep, takes away rep point for bad ones, how much you get to gets taken away depends on the status of the one giving it. Is that clear? You don't get banned or nothing over rep, its just a thing to do I guess.
I'm not the one to be anwsering this. Next......
