@bha19,
I am not a Facebook person soo..... the phone is INFINITY TIMES BETTER. You get things done. I was looking on Craigslist and tried to talk with them one-time. The person on the phone one time clearly was a scammer, and pretended to be somebodies secretary. Point being is the phone is a lot better then actually using email. I got more things done over the phone.
The problem with facebook is that their idea of being open in communications. Making it look like a phone call is not such a big deal.
Because of this pattern even Ebay, will give your contact information to people. That buyer/seller might choose to call you.
Again same thing with Craigslist. Usually phone numbers is the better way to contact people rather then E-mail. E-mail I get bs especially from middle-men ( people ) .
Is that a scammer? No I prefer the phone nowadays because email gets me nowhere to be honest and your phone could leave a paper-trail mush more accurate.
Just be aware of the location and the number they are using.
