Ok, I seem to be having problems with a yuku member. At first he was being really nice and just asking me normal questions, but then he started asking me really personal questions that made me uncomfortable. I told him to stop, but he didn't, so I blocked him. But just recently (today?) he messaged me using another account. I blocked this one too, but how many more times am I gonna have to do this? He has even followed me to some of the boards I am a member of. I know he has every right to be there as long as he follows their rules, but I don't like it. Any tips?
