Not sure why you were quoting that, Mex, but I googled the bit you quoted to get the whole story. Here it is if people are curious:

Q: someone at ft lauderdale is using the 2002 harley davidson ultra classic trike $4200. to spread what looks like a virus when one copies the ad.

A: I have not looked at the ad, but all I can say is Ive had ppl accuse me of having a virus in my messages. I was using a tracker to count how many people were looking at my ad. Nothing malacious. But eitherway, I have stopped using the tracker. I think its just antivirus/firewall software thats a bit paranoid.

So, apparently back in 2009 someone included a tracker in a craigslist ad and someone else's antivirus pinged it.
Mex, are you saying that you don't use craigslist because of this, or things like it?
Or are you thinking it has something to do with searchtempest?
Searchtempest is just google for craigslist, nationally and maybe internationally.
