I usually pop in once in a while and it is sad to see what is happening. I believe the best and best solution is that who ever wants to sell, buy, trade pay for commercial services like those of the sponser. (then we can get better bandwidth, blah, blah).
Even Cash convertors selling second hand items must have licence to sell and buy. And also seller must show teng ki (IC) when want to sell. (reasons known to all)
But all in all, "Stick and stone can break my bones, but names cannot hurt me". But it can kill a person intergrity and character. Words has to be chosen carefully even if you have a point to prove. ( I took half an hour to type this msg)
We know who to avoid, well at least for me. I would rather pay at the LFS and get the things I want and if it die, my fault. If it is not the actual stuff, I can seek compensation for misrepresentation.
Anyway thanks all for all input and lessons learn in this few weeks.
It has help a lot.
