Sovcit went to the airport with their fake passport, things went as expected for sovcit.

I've seen "pub crawl passports", where the intention is you get a stamp at every pub in town. I'm sure they work just as well in this application.

I couldn't imagine an easier group to grift from than SovCits except maybe evangelicals (and sometimes both intersect), so very probably.

I'd imagine governments would crack down very quickly on anyone making realistic fake passports. Maybe these are collector / hobby passports, like the ones some cities sell to tourists.
