When it comes to an account on Telegram and on two social media platforms - for example Facebook and Twitter, probably all bounty hunters have them, so it's not a problem. However, 3 posts a day on ech account, it will be quite a lot of spam. This type of campaign can have the opposite effect.
Anyway, what is the form of payment and how often it will be paid? Are they tokens of your project or maybe some fast exchangable crypto?
