Wow, all of this because of the word "Illegal" ha ha.
I think that word make sense for people in CydoniaX's position. When you are in charge of something, you stipulate some sort of rules, which people are meant to respect. When they don't, it's OK to say illegal, 'cause their actions are against that rules.
Now, are not "illegal" actions that it's going to put them in jail, but definitely will have all kind of consequences and its own "punishments".
Anyway, the main thing is that people should be more careful with the information they share and, obviously, use the common sense a lot more. I mean, giving your PSN ID and password, is the same thing as giving your mail and password to some stranger, would you do that? .... I won't.
