Time to necro this thread.
tl;dr for those who don't want to catch up with the thread. Delta was an alt of the scammer/hacker Tanner:
https://steamrep.com/profiles/76561198053214199
He opened a gambling site, scammed people, the dev shut down the site because he was also scammed. After some more scams which you can read about he then moved on to a new alt:

While this thread was dead I tried getting Delta and Lux marked as TannerMcMan alts, but steamrep no longer links alts to mains for some reason.
He's been paypal scamming people on Lux by 'selling' a Rocket League alpha account. Strazyyy found out about some other scam of his. Saw a comment on Lux' profile about it but it was deleted and I never looked into it.
Lux also made himself the leader of Delta's Tossup.tf group. Using fake giveaways to get fake rep on his profile and his own alts to prepare for more scamming

The reason why I'm necroing this thread however is because he now owns a site similar to tossup.
csgodirty.com
He then made this announcement on the tossup group http://puu.sh/oV4So/cb6cff92ca.png promising a knife he doesn't even own.
on the site it says "©2015-2016 | Obsinthe Systems All Rights Reserved" which leads to this profile

Though he's mostly scamming rocket league/csgo people atm he's been doing TF2 trading as well and has redownloaded TF2. He might return to TF2 soon.
