You have all probably seen this group "network" at some point. They send out invites to everyone. They giveaway bundle games here in mass quantities as part of their recruitment. They also advertise giving away AAA titles to whoever invites the most people to their groups. Sadly those giveaways are rigged, as they are not done on SteamGifts, but rather in his group's forum, and no winners are chosen truly at random as the system here allows.

But that's not what I'm here to tell you about.

First, let me show you exactly what I am talking about, in case you are unfamiliar with the OTG Network.

Original Traders Group
Original Curators Group
Original Giveaway Group
German Giveaway Community
Original Society Club
Duck Society

The above 6 groups are what's known as the 'Original Network'. It originally started as just the top group. It's recently expanded unnecessarily into the other groups. You can do everything the 4 groups do with one group, after all. The groups are also all populated by the same people, so don't let the numbers fool you. The Original Society Club is for the most loyal of his followers, where he supposedly does non-bundle game giveaways. Duck Society is...I don't even.

They are all run by a lovely fellow named SalzStange. His username here on SteamGifts is AngryErpel.
Confirmed with SteamGifts Support that this is not calling out..

SalzStange was recently outted on Twitter for trying to blackmail a developer for a free Steam Key. This kind of activity has been known to occur in this "network" but was covered up by his loyalists. When things like this happened in the past, or someone wrote a negative review for a game SalzStange obtained keys for, he would ask his loyalists to downrate the hell out of the review, which they sadly did. According to other 'victims', his loyalists were also asked to harass people that did not agree with SalzStange's methods or people who called him out on his bullshit. It's safe to say some are blindly following him in the hopes of free games. This is, of course, unacceptable, and since this was brought public, some of his loyalists left the group. Namely a few (most) of his admins and even a co-founder. He now has a new set of followers and Admins/Mods, and they are still up to the same routine.

SalzStange thinks giving away games is charity, and refers to his groups as "the biggest charity groups on Steam".
Charity is helping people who are less fortunate (IE Homeless, starving, etc), donating clothes and food to homeless people, or volunteering at a shelter....things of that nature. Not giving away games to privileged people on SteamGifts. He lists hundreds of giveaways for bundle games and games he's received from devs here on SteamGifts. The bundle games he asks members to donate to him so he can give them away here or in his group's chat (this has been confirmed by many former members). Either way, he is unfairly benefiting from contributor value here on SteamGifts because of this. He is currently a LV 9 contributor here on SteamGifts.

There is a reddit thread where a lot of people have come forward to share their experiences with SalzStange and his groups. and there is also a NEOGAF thread.

Proof, evidence, chatlogs, examples of his behavior and other things.
Take a look at these and find out for yourself what kind of person SalzStange is. Don't listen to his long-winded excuses or lies he's posted here and elsewhere.

If you are still a part of this "network" I advise you all to leave to avoid being dragged down with him. It will happen eventually. WGN got shut down for doing less than this.

If you would like to combat this network and it's practices, there are a number of things you can do.
If you are a member of any of their groups, or any of the groups that SalzStange associates with (Such as Hookups where he is an Admin), simply leave them. You can also share this thread with people on your friendslists who are members of these groups and advise them to leave as well.

TL;DR:

SalzStange threatened a dev, got caught, and is still trying to lie and cover up the facts, acting like he did nothing wrong.

He claims to be an adult, but is refusing to own up to his actions. Everything we do in life has consequences. It's time he faces them.
