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

Add the eth to a farcaster LLM bot that people can try hack into by getting it to convince it to transfer the eth to a wallet. The bot would have tiered protections to ensure it’s not drained in a single go.
I’d use all data collected from interactions and publish a white paper on building robust and secure bots.
