It has nothing to do with the country per se, but everything to do with the specific jurisdiction handing down the fine or suspension. No jurisdiction is required to honour the ruling of another unless the ruling is something major (drugs, race fixing, etc). Bad riding or driving in one place doesn’t usually follow a person, nor does non-payment of bills nor failure to comply with claiming and/or purchasing rules. I know of people racing in California who cannot race in Canada for example and a few cannot race anywhere BUT there. Conversely, I know people racing in British Columbia who are definitely not welcome anywhere else in Canada, but can race in the States. It’s a complex system made up of national and regional governing bodies, and mostly, all that can be upheld are what comes down to criminal behaviour in some degree and most rulings just don’t reach that far by the nature of them. You cannot equate being late for retention barn or late to the spit box with a drug positive, horse or human or assault or fraud and the same applies to rules applied specifically to the actual race - a guy can get days for cutting someone off at Track X but can still ride or drive at Track Y one state/province over and sometimes those rulings are ONLY for that facility so the offender serves his penance for WEG by going to another track not under WEG umbrella. See what I mean about complicated??
