I got a text "Heyy :)"...didn't respond.

I got a text "heyyyy (my name)" from this number and when I texted back and asked who it was all they said was to add them on SKYPE and their weird ID. Kind of creepy that they knew my name...

i got one exactly like that

Never text back to unknown numbers.  Always google first.  Got "Hey" but no name.

I just got a text asking to be added to mu yahoo. It said add samanthachick9
