I wonder if its possible to completely turn off ability to make ANY comments and only allow PMs. May lighten load on Mods so they can concentrate on scammers. Even our discussing this issue here has degraded the poor OP's post for which we should all apologize.
I agree with Nameless Hunter. I posted an ad here for an antique shotgun and some clown had to badmouth it and brag about all the similar guns he had. I'll still buy here but I won't sell on this site.
One local gun site I’m a member of only allows the seller to respond to their for sale ads. If you have a question or simply want to buy the item you pm the seller. Keeps the ads from getting cluttered with unrelated comments.
