Scammers often start with "Is your ??? still available?" Think about that. Why would they even ask that if the ad is still posted? Why not just call/text/email you and ask details if there is any real interest?
Any contact with a scammer just opens you up to getting your identity stolen at the very least.
I get "Is this item still available" on almost every ad I post on Craigs List and quite a few on Racing Junk. Now they are even copy/pasting in the actual item name into their sentence.
