Where are those giveaways coming from?

There are a few created by 1-2 users. I guess it probably was something they bought long ago and they decided to just give them away.

Green Man Gaming Codemasters Woot crate

Here's what you get inside each w00tcrate:

Overlord - You want to be evil? Now's your chance, lead your armies to victory over those disgusting forces of light.
Overlord II - You want to be even more evil? Overlord 2 gives you that chance, give good a damn good thrashing.
Operation Flashpoint: Dragon Rising - Military simulation meets FPS in Dragon Rising, take your team to the battlefield in full co-op action
Operation Flashpoint: Red River - Co-op returns in the sequel to Dragon Rising, with class-based military combat to your heart's content.

$0,03 on shady russian site, non-bundled on steamgifts so people farm cv

3 cents at russian leque shops
15 cents at dailyindiegame.com
was previously in a bundle at dogebundle.com

it's actually a fun Paperboy clone game with lots of 80s nostalgia references in it

Thanks for your infos, Mihey3Z and stlpaul!

can it be related to the patreon thing mentioned in this video's description? https://www.youtube.com/watch?v=KwXSWDCc_XY

It was here (but all 2000 keys are gone):

https://giveaway.su/giveaway/view/949

I'm not sure where it is coming from, but it is currently listed as unbundled while it is cheap on DIG, so I imagine they are trying to get CV out of it before it gets added to the bundle list.
