Ah, just as I predicted, the old give-us-some-loans-or-we'll-ruin-the-integrity-of-the-league blackmail. And as I said before, a simple solution. Hit them with a huge penalty points deduction (50 or so), let them bring in a few loans, but have all remaining negative points carry over to next season in L1.
Certain relegation for the Cheats, but still an incentive to at least try in each match.
