Although to be fair, the way that bounties work back then were still effective, not sure if they still do Twitter, Facebook, Reddit bounties, but with that campaign, you have plenty of audience that could open their ears and eyes for your project depending if your project is worth visiting.
Have you seen the current state of the bounty program on the forum? there are too many newbie - members there, and after some time ago I checked, there are lots of accounts that are connected to one another, which means they are just taking advantage of the opportunity. I'm still in my opinion that the bounty program is no longer relevant here, it's better to use another platform. But for signature campaigns, it's still relevant and effective.
