I deal with people like that all the time. They get blocked. I've posted about all my bad encounters on armslist here as a warning to others.Then, there are the guys that DO want something for nothing. This guy usually has no intention of buying, can't really afford to buy what is being offered, and is probably just throwing shtuff against the wall to see what sticks. This is the guy that irritates me. This guy usually doesn't communicate well, either. Messages are usually so brief as to be downright rude. The older I get the less tolerance I have for this guy. I usually tell him something along the lines of, "If I wanted to give it away I woulda just taken it to Goodwill.
Some people are just rude.
