Gudoks

The bet was that people already active in reward communities would follow a brand's channel for a small cash reward, and that checking each follow by hand would keep those followers real accounts rather than bot traffic. The pitch was that a client never hands over account credentials: they give the public URL of the channel they want to grow, and Gudoks does the rest.

Gudoks never asked for a client's social account login. A client pasted the public URL of the channel they wanted to grow and left an email address, then signed in through a link sent to that email, with no password to set. The campaign form covered Instagram, Facebook, Twitter, TikTok and YouTube, and let the advertiser scope the audience to Korean users only or open it to everyone. Rewards were paid in Korean won, and only after a participant submitted a screenshot of the completed follow and it passed review.

The team's account is that abusive users showed up and that reviewing their submissions became the expensive part of running it: every follow needed a person to look at a screenshot and decide whether it counted. By that account the cost of policing that queue outran what the campaigns brought in, so Gudoks was shut down. The domain no longer resolves.

The thread here is a lesson, not shared code: pay a reward only against evidence that the work actually happened. Reviewhunt, three months later, took the same shape into its Nomadtask era and ran into an abuse problem of its own.
