My Uplay account regularly gets hacked, I've just given up on it at this point lol... It's way harder to hack a Steem account though unless the user is careless with his password.

I don't believe those Steem accounts have been hacked for the simple reason that they are all brand new and all their interactions with the blockchain are just flags and resteems. I could definitely see the value in some of those accounts names though but the actions associated with them would make them worthless in my opinion.
