To reduce the number of scammer that reply to your ad, do as I do.
When I post an ad on CL I disable email replies and put in the ad MUST CALL, I then give a google phone number that is linked to my cell phone, scammers won't call, they just move on to the next ad they can email.
When I put the phone number in the ad I mix numbers, letters and written numbers to foil automated phone number mining software. This method has worked well for me, I very seldom will get a call that is not a genuine buyer inquiry. If they want additional pictures I ad them to my CL post, never send them direct from my email.
