Alright. So a little bit of history lesson. Please bear with me as I present a few case of witnesses.
1.
http://steamcommunity.com/groups/DuelSkins
DuelSkins.com is "an online csgo gambling website, offering coinflip, roulette and a nice community."
This site was quite popular but as of a few months it has been acting weird, being on and off abruptly. Folks have complained about losing their trades and all their items that they converted over. The admin of the site, WDeV, is stating it's just downtime, but clearly it's bigger. Folks have threatened to alert the police to get their stuff back, and as of now the site redirects to ************, a steam reseller thats actually banned here at GAF.
The administrator of DuelSkin's Steam Community is named "CSGOLotto [3]".
They're one and the same.
Viewing WDev's Steam profile also shows this evidence that they're one and the same. Also operated as CSGOLotto.net (which also redirects to the banned keyselling website).
They also operate CSGODices.com, another CS:GO Gambling website.
