What’s this account doing? [BOT]

Question

Does anyone have insight on what this kind of strategy is and how it’s effective?

What I know for sure is they use Jito bundles for all or nothing transactions with an entry/exit that always returns profit.

They also only trade directly on Raydium AMM pools, no cross route arb.

Some pics below. I’m writing a bot myself and this strategy definitely caught my attention, I’m just trying to gain more knowledge about it.

My understanding is this bot performs sandwich attacks using a dodgy/compromised RPC which allows him to see other people transactions just in time. That bot is everywhere and literally printing money by collecting a tax on everyone. I had a look at some of the transactions, I believe the bot Jito bundles the victim's transaction with his own, also he uses one custom program..Pretty neat stuff. Hopefully that dodgy RPC will get caught soon..
