Sounds like you are describing a bot net to gain influence twitter-style. I think what makes this different is the need to commit sats, and to have a lightning node per account for the authentication. Raises the cost of sybil attacks, with the idea that it makes them economically infeasible.
Can't you create accounts with throwaway emails?

How would those accounts acquire sats for upvoting? They would have to have their comments upvoted to get some sats first. Overall it's just harder to gamify, I think.

They would acquire sats from the main account, sending sats to themselves between accounts.

True. Maybe there shouldn't be email logins
