With lots of leagus having self inforced rules, such as forcing people to use certain tyres or things like two tyre compounds in the race and so on. Don't you think the league host should be able to disqualify anyone who doesn't follow the rules from the race results.
For example, if you have to use at least two tyre compounds and someone goes S-S-S and finishes 6th. The host should have the ability to DQ them and allow p7 down to move up the standings. You can only do so much with warnings and telling people to pit on the first lap.
