No. Not inappropriate in the least. But if this guy sending you messages of any fashion makes *you* uncomfortable, just unfriend him or whatever. I personally think you're reading something that is not there, but deleting him certainly shouldn't be a big deal since you two don't even know echother.
Good grief. I think this thread conjured my cyber/stalker friend. Here's the latest (got it today):
"I must admit I got excited when I got ur reply to the phished email. I miss chatting with you. That said, I dont expect to hear from you again. I dunno if I made a nuisance of myself or there's some other reason we stopped corresponding. I do hope you are happy and healthy. You're a special lady. Take care. Email if you want, please. "
Nothing inappropriate, but on top of he other emails/texts very pushy.
