Maybe you could leave the question and edit with solution so next time someone with same issue can use it

I wanted to report someone for harrasment but you can block people so thats allowed. Since it were merely pms. Still I think its unrespectfull and this person should be chatbanned. But I read the rules so I deleted thread.
