Ok so this guy on Yahoo messenger contacted me. He was nice to start off with. Then he started calling me nutter and a mental case without me doing or saying anything much at all. He said I needed help and I keep blocking him but somehow he keeps getting through. All I said when he asked did I like sex was that I had no interest in it. He then said I had mental health issues and that I was off kilter and said I needed mental help. He threatened to find out where I live and stalk me too. It made me feel upset and really sad. What can I do?



Sorry you have had this disturbing experience.
You say you have tried blocking , but he still gets through? I expect you went through the process of googling 'yahoo abuse'and following instructions?
There is a place where you report 'messenger abuse' as well as blocking it
However they say it is an automated process 'due to large volume' of abuse reported. Hmmm.. a sad sign of a minority of people who are out to misuse modern technology at any chance they have and abuse others.
More general advice:
Dont take it personally.
Keep cool.
Don't respond.
Go completely 'quiet' and contact trusted friends via an alternative identity/via emails,etc. Hopefully you haven't shared too much personal info...
Stay 'apparently' off line or preferably not signed on at all, so you don't feed his obsession.....also then you won't see if he is still trying to 'bother' you and have that worry.
Eventually that way he will be sure to move on 'to new ground', where he can get responses he craves.
Good luck,
