An idea of the region may allow for more insight. But I'd say spooky suspicious. Have you made appointments with any of them?

their handle or email you using their account, I would be very suspicious.  I normally don't tell providers I saw their ads on TER because I don't want to compromise my identity on here.  But if I do tell them and they ask, I would be willing to send them a private email to verify.  These are trouble times and better be cautious and skip an appointment when you are not comfortable.  Just me 2 cents.  

Be careful, there is allot going on that we still don't know about. I am sure that if they really want to see you, they will give you what you ask of them. Nevertheless be careful and use your inner guide. Better safe than sorry, just my 2 cents.
I have nothing to hide and if a lady needs my address or work number to feel safe, I don't mind and I am glad that she won't see just anybody. It shows that she is not needy and that she is careful. Hey, if they were to approach me with a question, my reply would be, I don't know her. They never saw me do anything wrong and I am very successful and don't care what other people think. Hey, I'll tell you off the bat, I have seen so many women that I don't remember and of course you can have my work number, what are you gonna do? Tell my secretary that I like a different piece of meat every week? Let' get real here. You ladys have more to worry about than us. Those idiots don't have a clue as to what you ladies probably have to put up with.

Whose your daddy, girl?!!
