Blockstorm

Free several times, yes. I understand one of those happened recently, maybe a day or two ago.

IndieGala had it, maybe some other site as well. But yes, it was a freebie.

Yeah if u give it away .. ull get ban. Same with a few other games. I been asking about it. The game considered free. Though like deponia.. i dont recall it being FREE, but only from a few bundles.

always search the forums and try to create a new ga to see if a game is enabled http://www.steamgifts.com/discussions/search?q=blockstorm

It's on IndieGala's permanent giveaway rotation. When you redeem an IG giveaway, it will often give you "a chance to win" Blockstorm, which the "chance" is one click per 5 minutes that gives out a key usually within 10 such clicks. Tested it on 7 accounts recently, during their last Kraven Manor giveaway, just to see how easy it was to "win".
