Since there are no rules for private selling or buying I can put up with all kinds of garbage. I don't mind extreme low ball offers (I just say no or ignore them, I don't blame them for trying however) and I don't even mind trade offers when I say 'NO TRADES' etc.... no problem, doesn't irritate me... 
Now, the ONE THING that annoys me however is the guy who goes to GREAT LENGTHS in many PMs or emails to 'sell' me on the idea that I am a complete ass-jerk if I do not take his 'low ball' offer....and when I don't take it? He writes a scathing angry hostile rant......now THAT pisses me off!
This used to happen only once in a blue moon....now it seems like it happens every single time I sell something
