I love how these Russian devs do not even think about at least pretending to mask what they are doing. :D

Just a small update: it was a CV farming operation for SteamGifts after all, it was just the dev was selling CV en masse:

SteamGifts removed all contributor value from the DLCs retroactively (including another one, a 200-dollar "Nuclear Edition"), so another shady operation busted.

Neither of the three free As (AVG, avira, Avast) are particularly good. Avast does have a tendency to jump every gun though. It is both good and annoying as hell.

The news is already spreading, I just came here to check if someone posted about it.
The cards are delisted, so it means Valve officially stopped doing any kind of business with him. It seems all games were caught, regardless of company name switcharounds.
Finally Valve doing something good, for a change, even if rather slowly.

Well, Sentinels ought to know what they are protecting, and considering how many people monitor indie releases here, a good bet is that someone may remember bumping into that.

Very hentai. This game essentially begs for meme reviews.

Denuvo technically is, but that doesn't necessarily means it is malicious. Then again, in IT, virus is usually defined as hidden malicious code, so… yeah. Take your pick. :)

Looked at the thread, 11/64 detected anything and the the only one in that least that was even remotely credible was Symantec.

But for the core question itself, yes, Steam could be used as such, because the first time I ever heard it is supposed to have an antivirus measure was this topic. And yes, Valve should do ensure to protect its customers.
Then again, we saw that the average Steam gamer is not that different from the average console gamer, and we also remember the huge repercussions Sony faced after someone leaked millions of subscriber payment data. Twice. People went back immediately spending money on the PS store anyways.

Sadly, those seem to be made by humans. There could be shenanigans involved, but bought reviews are a lot more generic and have even less variety. When they are even written in English.

The DLC? Probably, since the game's one-dollar status, combined with SG's value dro-off system would mean little to no CV gain there, as he already experiences. He sent 66 copies of the 20-dollar ne, but since CV flatlines around the 15th copy, he is still at level 3 only.

On the other hand, that account entered only one giveaway, so it is not like he is actually trying to get into high-level or group giveaways, seems like pure ownership boosting.
