I fall into the "above average" category, as I constantly trade. Remember the slash means "or" not "and."
This is _not_ a place to discuss others, this is for everyone's benefit. If you don't want anyone else to know, just vote and stay anonymous. I know this is kinda silly but I think some people need to accept what cheating is...
And no, not ALL trading is cheating, I'm talking about trading for valuable items. Photon Drops and 9* and even some 10* items don't fall into the cheating category...Use your best judgement and consider what you traded to get what to help you decide if you're a cheater or not.
Also keep in mind, if you trade a rare item to a duper, whether you knew that person duped or not, you just helped that person cheat. Take that as you will.
