So it was some person i dont know who was responding to a Craigslist ad and sent me their number via email. I sent a couple texts and they stopped responding. I emailed them today and the guy told me i sent him texts from two different numbers. He had deleted them already because it scared him. This is a new one. Can't figure out how i did tbis myself. So is tbis a scam or what?
