Yes, it is kind of weird, since I've read a lot of posts from people who said they got banned out of nowhere.
At the same time, I've been playing on Plutonium for 8 years, and during all that time I've never been banned, not even once.
In fact, back when non-Steam versions of the game were allowed, I used one. Nowadays, I've bought all the older Call of Duty games on Steam.
