It's against the rules to do FIA races on multiple accounts, and really not fair on the people in the region you don't live in.
To put it simply, I don't care, and you shouldn't either. Allow me to elaborate.
I thought about this for about a year before creating an EMEA account and deciding to participate in some FIA races. During that time I participated in many seasons of FIA in my own region and became very familiar with how everything works, the ranking, the matchmaking, the points, and yes the rules. I also learned that many more people do this than you probably think. I was surprised to learn that a lot of very good drivers have accounts in multiple regions, or every region.
So, on to why I don't care and why you shouldn't either. Because it affects you in literally no way. I am nothing more than a competitor, just like you, just like everyone else in these races. It is no less fair than racing against anyone else who joins the lobby. Let's pretend for one second that I am good enough to make it to a live event. If I qualified that high in EMEA (I can't), I would not be eligible for the spot because I don't live there. In which case, the next person in line would be invited instead of me. So nothing will have changed, nobody loses out on anything.
If you care because I am racing against people who are mostly slower than me, then don't worry, those people only see me for approximately one race, and if I do well enough, I'm in a different lobby for the next race and they never see me again. And let me tell ya, there are some pretty fast B/S drivers in EMEA and a few of them have given me a run for my money, so I am not entirely out of my depth in low A/S and high B/S lobbies as there's usually a couple guys on my pace or close to it. There are so many lobbies in EMEA I've seen different folks in every FIA race and have only participated in one slot each day for a total of 6 races that I've used for practice before my own.
If you care because of the points system, I'll remind you that these lower ranked lobbies where all of my EMEA FIA races have taken place, are only worth 1000pts or less, most of them were worth much less. The difference in points between P1 and P2 and P3 and so on, is only 50 points in some cases, or even less! So if I win one FIA race, the guy in P2 only gets about 50 points less than me, and he still has 2 additional chances to join the same race later on that I won't be a part of. Not only that, but these guys aren't competing for a spot in a live event, they are only competing for arbitrary points which amount to nothing more than bragging rights. So essentially, these points mean nothing to anyone who can't qualify for a live event. I'm not taking their points, if anything I'm using FIA to gain DR quicker and get out of the lower lobbies so they are not outmatched. Being A/S now I don't think that will be much of a problem as the guys in this region are significantly faster than my own.
So there's nothing unfair about it. It's still a race against other drivers who all play the same game. They have a chance to beat me and I have a chance to beat them. If they win, they move up, if I win, I move up. The points mean nothing to people outside of live events, and if bragging rights are important to them, they still have plenty of opportunities to gain those points whether I'm around or not. If I'm standing in the way of somebody else's ability to score good points, then I don't really know what to say to that person except to get over it and stop blaming me or other people for their lack of performance.
If you continue to concern yourselves with things like this, I'm here to tell you that's your choice, not a necessity. It does not affect you, so that is what I would call wasted energy.
Good luck!
Very happy with the result
