Plenty of cheaters in HC as well - just an FYI. Make your settings "Friends only" or "Invite only" and that will help.
As for me, I am a legit, recently returned HC player - been back 4-5 days now and am P40. I don't generally group up, but if you are legit and HC, feel free to add me for the "free Legendary Gifts" that can drop and be sent to those on friends list. I have been sending out around 3-5 daily, but then again I am not playing on high torment level (yet).
