When I put an ad on CL I include the following:

"Send phone number and I'll call you. I won't reply by email or text".

If someone seriously wants what I listed, they'll send a phone number.

I believe that a lot of CL and Marketplace responses are phishing for personal info. You'd be surprised how many people say, 'what's your address' and then disappear when I reply that we can meet at the local CVS parking lot.
