that is quite disturbing

i know... and there is one that he has a picture of "someones upper arm" and every video where my arms were visible he commented on them :S

thats why i want to know if i can block people...

i say block him

i have, but does it COMPLETELY stop that guy from seeing my videos, looking at my channel and other youtube things?

isn't sure but blocking him is at least a step in the right direction

thing is, he may still be able to login as unregistered user and access your videos that way.

It should do, it's like when videos are set to private only certain people can see them so he shouldn't be able to see your videos

or your channel

Thanks. last night i was searching all through youtube help to see what it saidl but it didnt have anything so i was really worried.

oh ok, if it is a private video and you block someone, then he won't be able to see it at all.
