rake race bots?

Been noticing some wild surges on the rake race leaderboards lately and I can't help but think bots are involved. There's a couple of accounts always clocking insane hours, like nonstop grinding at a pace that doesn't even feel human. Either they've got the strongest coffee on earth or something shady's up. Doesn't even look like they're playing decent hands, just pure volume.

I get that rake races can draw out the crazy grinders, but this is next level. Is anyone else spotting patterns like this? Curious how you guys spot bots or handle these situations. Do you just avoid races when things get fishy or is there a good way to play around it?
