MW2 VAC Banned?

[Pozzuh]

I was mw2 banned while activating black ops. I can still play black ops but not mw2.

If they suspect you to violate the Steam License Agreement and you have a VAC2 ban for a game on that account they disable it.
@d0h! had it, I had it, many others had it. (they once disabled 3 or 4 accounts of mine because they suspected me to be a cheat developer because I bought games via an @itshax.com emailaddress on those accounts; contacted them, they only restored the one that was worth the most (>$2000 at that time) and for the others they told me to stop cheating (those are still disabled (without VAC2 bans))).

i have some account, pair of this was used only for free-week and some demo.I was able to play homefront demo for each account, changing only stats from one to other but after trying trainer on "cheating account" i reach ban even for other account (is not ban on record but i see it in game log).
Anyway steam make logs for everything and if they was suspended maybe 'cause "share account" not for cheat or ban, phps you can change mail adress.

Steam ban game engine, Mw2 and BO are not the same engine, better use new account if you own mw2 banned before installing Mw3
