Ive just re-discovered that the guy who has been annoying me is called rainbow_sleeves here.

He requested my number and photos again but i quickly remembered who he was. I dont know why he did that, i presume he was hoping i wouldnt remember him and would send them on. He has never seen what i look like, so he is stalking an idea of someone. Although now im worried that he registered under another name just to get me to send him pictures, so im a bit stuck, dont want to trust anyone who contacts me. Also he'll probably read this and get off on it. sigh. can someone please help me here?

i dont know if its okay to post his username here, if not please delete, but will someone please stop this guy from contacting me?
can i block him or something?
he is FREAKING me out and i dont know what to do. this is the first time in four years of doing this that i am genuinely a bit scared of someone. he knows nothing about me except my phone number.
He claims to recognise my voice on the phone but he was just trying to scare me.
