Thanks for this.
It appears that some asshole has hacked my main ilesmark youtube account. This isn't the first time this has happened to me and youtube appears powerless to stop it from happening to increasing numbers of other people, judging from what I have read on other forums like this one.
Thus, rather than have all my vids in 1 acccount, I am going to have them in lots of small separate accounts, all beginning with the name ilesmark. Needless to say, they have LOOOOONG passwords! That way, if the hacking occurs again the loss will be capped. Shame to have to do this, isn't it?
One question - what is a keylogger?
