Import rules should be adjusted according to the region. For some orgs and region it's WAY TOO EASY to import someone. The more imports there are the stricter the rules should be. either:
Make it harder for orgs to acquire the imports.
Give imports a limited timespan on the region. Once you're done you're not coming back again.
limit import slot to just 1 not 2, this includes dual nationalities ( you can thank scarz for this )
I don't like these extreme meassures either, but istg some of these orgs are just asking for it.
