Maybe possible duplicate thread

Row 2,3,4,5,21,54,62,70 used

Tried or 10 or 11 of them (Until steam blocked me from trying more). Everything is activated.

Costume Quest (18) and Monster Loves You! (46) were already used, but thanks for letting someone possibly pick up a game. :)

All of these are duped:
Rows 11 (Blackwell 2), 12 (Blackwell 3), 46 (Monster Loves You), 84 (TinyKeep), 89 (UnEpic)

Rows 15 to 18(dungeon defender and dustforce DX), 20(Eldritch), 23(Finding Teddy), 62(Binding of isacc), 68(Thomas was alone), 77(VVVVVV) also duped
Too many attempt XD

You can most likely cross out all of them. I seriously doubt that someone with several accounts made to auto-farm keys haven't gone through all of them already and activated what was left. If you don't encrypt the keys somehow and post them in the open, they get ninja'd in minutes.

i have tried bloodsports and vvvvvvvv, both duplicate

Guacamelee, Prison Architect, LUFTRAUSERS, Risk of Rain and Tower of Guns already used.

26, 44 both taken. I also agree with talgaby, next time you do this, make sure that we have to do some math or something in order to actually redeem.

Tried Fez, The Inner World, and Thomas Was Alone but all gone. Thanks for this anyhow, cool stuff :)

45, 65, 64, 58, 66, 72, 61, 52 taken.
how are you going to keep track? oh well, good luck :)
better mark them out before you delete them. so the numbers don't change

These are already taken:

Heavy Bullets
La-Mulana
Organ Trail: Director's Cut Steam key
Osmos
Robot Roller-Derby Disco Dodgeball

OlliOlli is a dupe.

The following are all used as they return a duplicate key error:
Mirrormoon EP
Over 9000 Zombies!
Runers
Stardust Vanguards
Starseed Pilgrim
The Blue Flamingo
The Novelist
Ticket to Ride

Monaco: What's Yours Is Mine, Super Meat Boy, and Shattered Planet are all duped.
