Stop Ridiculous Administrative Faction

1.13.2 compatible. Whatever, Paradox has disabled AI be forced join a faction to continue to let others join. This mod should no longer require a subscription, but it's still available if you don't want the influence mechanic.

I have made a new mod to rebalance this mechanism: AI that has been forced to join a faction will not continue to use influence to get others to join. AI will not use influence on players to force join. Stop Ridiculous Administrative Faction Alt

=======

According to the 1.13.1 update log, Paradox has added a mechanism that forces the faction to disband if everyone in the faction does not want to rebel, which partially solves the faction problem. Without this mod, the Byzantine emperor should not have to go through a civil war every 10 years to suppress factions. But the influence mechanism remains unchanged. If you think that using influence to brainwash is too outrageous, you can still add this mod, which is available for 1.13.1.

=======

This mod disables AI under administrative government, from using 500 influence to force another AI joining faction for 10 years (and this AI will do so too). This is the reason everyone, even +100 opinion on emperor, is always in faction and do not quit.
