I never really cared. I remember getting a 3 day time-out because someone was selling a car in the classifieds and I commented how nice it looked. Mind you, the ad was the second ad down so it wasn't like I bumped it up to the top over a page full of ads. Seemed kinda over the top to me.
I like it when people comment in my ads that the sent a PM, because I don't stay logged in all the time.
I got a 3 day too once for asking the guy if he would hold the gun a couple days before I could get to him. I was told I should have PM'd him.
