I got the same thing like a month ago I asked who it was and they ignored my question and said their phone was about to die and that I should get on IM. I asked why don't you want to tell me who you are and they stopped texting me. And then today they texted again saying hey sara.... This is annoying

I received the same "hey ;)" text.

Sent text no reply

Same here. Even knew my name.  Then she asked me to log in to im and told me her id.

Just got a text message from this 845-868-4072 saying hey :). I don't know who they are.
