People doing something that part of them knows is shady, don't like someone shining a light on it. They react strongly.
Its like a guy that gets caught cheating. Most of them don't just take their lumps. They attack the woman who caught them, for "going through their phone" or whatever and try to turn their transgression around on the person that called them out on it...
So just add them to ignore, move on, and your time here will be much less drama-prone....
I will gladly "take my lumps" if you can prove I am a "flipper". I again call you out, prove your statement. Show me how much information you have on the members of this site. Tell me how you know about sales that were done in private. Otherwise, you are nothing more than a blowhard.
