Has any one ever got steam game revoked ?what game and why?

Valve usually revoke games which were bought with stolen credit cards, and the original owner chargeback his money.

Price error on GamersGate.

Warlock 2 and Penumbra Collectors Pack

not that i know of. do you get a notification?

DayZ, revoked due to chargeback money.

Contacted Steam Support, with fully detailed history, proofs, screenshots, trade history, etc

3 days later got all my keys back

Yes, from an idiot on SG chat who either did a fake giveaway or got instapoor and cancelled everything.

Got Watch_Dogs Deluxe Edition revoked because of charging issues.

Got my keys back but then the bad thing happened. Steam forced Uplay to ban the CD keys which are bound to my account. Since Valve doesn't give new keys with a new purchase my Steam account is banned for life for playing Watch_Dogs. I had a discussion with both Steam and Uplay support and neither thinks they're responsible for my problem.

Do you get games revoked from activate Russian games with vpn?

once had a game revoked because it got out of beta idk which one it was

I activated a key on a wrong account and they removed and added it to my other other account.

Got 3 games which I got as a present revoked due to some automated process on Steam so my friend contacted Steam, waited for OVER 2 weeks for the Support to answer and provided all proof they wanted but he only got the money back.
They wouldn't replace the keys instead or giving back the money, and that lead to a loss on his part as he bought the games while they were on sale.
To make it all worse, he gave over 15 games to others as he owns a giveaway group and all those games got revoked too. Now imagine having to explain to everyone what happened and all of them having to wait a month to get the games back.
Additional bonus- my friend couldn't replace the games during the last sale as his account was blocked from making purchases...

i traded with a scammer for a humble bundle gift link ..learned my lesson

got Escape goat 2 + Goat simulator keys from a trader for a set of summer event cards , after 1 or 2 months Escape goat 2 was revoked contacted steam and they refused to listen because it was a cd-key however I downloaded escape goat 2 and tried to play it before it got revoked and it didn't launch in my pc but I still had got a great game (goat sim) for a set of cards :3

Yeah, I once bought Game Dev Tycoon for a few cards. I was really surprised it was so cheap, but I didn't ask anything. The guy seemed legit, he had considerable amount of positive feedbacks. Played the game, enjoyed it and after a few months got a notification that the game has been removed from my library. It said something that the game key was stolen, or the game was bought with a stolen credit card.

I wonder, is there a sort of notification about a game being revoked?

Only twiche: SPACECOM beta (developer's fault) and Walrock 2 (GamersGate fault)

SPACECOM Beta only so far.

Thought soon should be having couple from Groupees.

I got The Crew revoked. It was a pre-order gift that I activated myself before deciding to go for a refund. It's kind of funny when Steam has a pop up windows telling you that you issued a refund for your own game since I obviously know that...

Dead Rising 3. A certain page had a bug, which caused it to be free. I grabbed it, just to see it the second day revoked

I asked for Brink to be removed from my account (because it was RU) and they did.

1) LEGO Marvel Super Heroes - won it on SG, was revoked a couple of weeks later. The giveaway maker is perma-banned because this happened multiple times in his giveaways.
2) Warlock 2 Exiled. I was gifted this one, and it got revoked. It was probably from the GG glitch.

Knights of Pen and Paper +1 Edition, got it from a bundle long time ago then like 6 months later steam removes it. Sent a support ticket in and they said they'd look into it. Get an email back 2 weeks later saying its not on their end, contact the people you purchased it from. I just said screw it, I mean I already beat the game and I got all the cards so meh.

Dead Island (Exploited Key)
Dirt 3 (Exploited Key)
Warlock 2 (GG price error)

Got my Ethan Carter revoked, because there was a mysterious chargeback somewhere between Valve and the trader's bank. It took a few days to understand where the money was, it ended with the return of the money in his bank account. He instantly bought another Ethan Carter for me, and did the same to each of his customers who where concerned. It was probably related to Steam's new currencies a few months back.
