yeah, my meetup buddies have guessed the same. It seems to be a script that looks for a cheap route for a circular rebalance. Then it simply tries to get as many Sats through all channels of that route as possible by doubling each succesful transaction until the first one fails. Then it halves the transactions until the first one is succesful again and so on... It looks like it might be lndg, at least that's what a meetup buddy said.

BTW, my channels outbound liquidity is completely gone now. So I guess my channel was the smalles within this route 🤣
