Does something count as an import for PRX? More just russian players in general in APAC but something is a good example I thought of, or does he count as APAC technically since Russia is technically in Asia but it is more of the Eurasia area.
You're looking at it the wrong way. APAC ≠ Asia and EMEA ≠ EU. For example, countries like Saudi Arabia or Kazakhstan are Asian counties that are part of EMEA.
It also works by countries, so one side of a country can't be from one region and the other from another, or else people from that country would have the advantage to choose region. So something and jemkin are indeed EMEA players. That being said it works pretty well everywhere but in Far East Russia which I believe is the only region in the world screwed by the rule

Every CIS team are a part of EMEA, central Asia is a part or Turkey, I think Kazakhstan is in the same situation as Russia : Punished by Riot, but they are probably par of EMEA
its hard to put it down in rules but in practice its easy to determine whos been playing from far east/living there for most of their life and who hasnt. maybe evaluate cases individually, so not choosing regions but asking riot, giving them your 3 year old apac account and history of residency etc. but ofc i get why the rule works like it does as well.
