Is everyone on craigslist a scam artist?

Pure scam, I went through this two years ago or so.
But plenty of honest people on craigslist also.

Lots of details here:

Craig's List Cashier's check Scam, How does it work?

I’m using Craig’s list for the first time and I think I’m being scammed but don’t know how it works. I just received a cashier’s check out of nowhere from a person I don’t know. I think this is related to an item I’m selling as I provided an address & phone number thinking it was real. Though the check is for far more than the discussed amount. So lets say the check was for the amount discussed and I cashed it, how does the scam work?

This might be the most important post in that thread:

Well on the bright side, 4 of the 6 items I listed sold. The piano just went today.
The cheap air hockey table we put out to the road instead and it went for free.

I added to the descriptions of my items: No checks or Cashier’s checks accepted. Already had a scam attempted against me.

This seems to help eliminate the scam inquiries.
