Why the truth is not in them ??

I wonder how many people have been told something by a buyer, that was no where near the truth....I hate to think how many times I  have been told that I will send a Pay-Pal tomorrow, or I'll send you a check tonight....and never do anything of the kind.....I've been waiting for two weeks for a check from a guy in Michigan  , I have sold a item 13 times on another web-site based on what a person has told me and never received the first penny..........Does anyone tell the truth anymore ??   I have one web-site that I do business on that has a 98% negative truth rate.....Isn't that a poor way to deal with people ??     What are your experience ?? 
Do to others as you'd have them do to you. The ones that do not follow this simple rule, are the first to complain when they receive the same treatment they put out.
This is only about ,some sellers.Not about world politics. Democratic Socialist  please ,this a a Site about Audiophiles, not Politics  ,let's keep it that way thank you .Not there  political views ,but there views on audio equipment. THE END.
I guess that I’ve been lucky... the majority of my transactions on 3 different sites all went fairly well!
isochronism    Some people sell about three items a year , so they know nothing about this type of business.....How many items did you sell last year......I sold over fifty items and bought over a hundred items......I would have sold a lot more if it hadn't been for people with false visions.....
I had an experience 2 months ago with a man who turned out to be a middle class realtor in his 40’s (I looked him up).
He agreed to buy an amp from me, lowballed me and I agreed to pay the shipping as well. He was supposed to pay the paypal, or else use another method.
He sent me the money via paypal right away, minus the fee which was another $50.00. I didn’t touch the money, and immediately wrote him back saying that wasn’t the deal, either pay the fee, or go friends and family or send a check.
Within seconds, he sent me a flurry of emails calling me a crook, a thief and a scamming little b---h.
Civility and reason are just non-existent with some people. It was very upsetting.
