That's entirely possible on buses.

> Current law allows organizations like the Los Angeles County Metropolitan Transportation Authority (Metro) and the San Francisco Bay Area Rapid Transit District (BART) to issue prohibition orders. BART is the only such agency that has actually issued prohibitions in California, giving out 1,118 such orders from 2019-2022. About 30% of orders issued by BART in 2022 were for battery or threats against riders.

Curious if these bans are actually effective.
I can't imagine how this is enforced. Clipper cards and cash will get you on any bus without any sort of check to see if you're allowed. There is probably a lot of overlap of people who get banned the people who skip gates and fares.
