Well until I saw a comment below reitterating that the bots interact with blockchain and not the UX so this may not be possible.

this idea got shot down as the bots do not need it anyway. They interact directly with the chain, not through the interface. From what I have heard, there is no way to identify a bot from human. I keep pushing this point though.
The only other solution I can think of is randomly changing the voting period for max reward per day using voting information from the previous day.
I am not aware of a way this can be done (technically). If it was on the blockchain, a bot would be able to read it, right?

I wouldn't recommend it. However all information on the blockchain is open we can have guidelines for bots.
