Is it illegal to give away money to followers?

What if I said I would give 1 ETH to a randomly chosen follower this Friday? 

Screw it, let's do it. I'm gonna give someone 1 ETH on Friday. 

Only rule: Must Recast this post with what you'd do with the ETH

I will launch my pre-planned project about scam alert which basically will be a safegurds for newcomers in crypto world. Mostly farming and airdrops are full of scams right, i wanna demolish them by reviewing system, so all project will have points based on their previous step.

This project is a much-needed initiative in the crypto space! A transparent review system will empower newcomers and help them navigate the risky landscape of farming and airdrops. Looking forward to seeing your progress!
