Quoted from flynnibus:Yet somehow in bizarro world we celebrate the harassment of sellers as 'do good' activity to help us all.
One man's "harassment" is another man's "the emperor has no clothes."
The operative issue here is:
1. Don't personally attack people
2. Respect other peoples' right to have different opinions
What you are advocating is that other people should not be able to express their opinions if that opinion might interfere with somebody else's commerce. In order to impose that rule, you'd basically have to ban all opinion on everything on the entire board.
Granted, if someone posts a game for sale, and someone responds with "Shazam" or "$10k by Christmas", that's provocative, annoying behavior that doesn't really add a whole lot to the conversation. But I don't know how you can realistically outlaw that kind of behavior. It seems to be part of the mindset of the community.
It seems to me, it's easier to be a big boy, suck it up, deal with the occasional snarky comment, than it is to try and get the whole world to conform to what you think is "appropriate behavior" when efforts like this have never seemed to be successful in the past.
