I didnt realise how to block someone on IP, and I have not needed to, but I have some female contacts who have perverted/predator type people bothering them, anyway its really easy :-

on the icon ( picture ) of the person you want to block you have an option to add them or block them see picture below, thank you Lea for letting me know, you rock :)

I think perhaps IP needs to  blog this to let everyone know as it seems its not common knowledge.

 

Let anyone know who has issues with idiots on IP and keep this place nice fun ;)
