But it is not so easy to go from 150 sats to 50k sats which you can tip. For that you have to win the max bet of 150 sats with 350x multiplier and the odds of that happening are very low, less than 0.3%. One should have dozens of alts to abuse the faucet that way and I think that's easily traceable.
For me it is not that easy to start from faucet ,which is above 2k sats to reach 50k most of the time but some times i do reach it pretty easily ,so it is not an impossible task as you say so and even with 150 sats it might be possible as i have never tried it .Looking at the price of bitcoin they have to come up with a solution to block these abuses to extend their profit.
