Aside from popularity change based on how much the player bans I have other ideas my character would do (and some mechanics which come from it)
1. I would unlock the 83 step verification process (its a real thing, thought rarely used) - I'm thinking that there will be a verification mechanic which would essentially be adjustable 'migration policy', verifications would happen by themselves very slowly which would increase the userbase but the player can also speed it up by taking up the verifications themselves and choosing and checking users to be let in or not (in a papers please sorta way probably) and allowing the right person would raise the userbase but you run the risk of allowing the wrong person which would lower stability or have some sort of custom events (if said user is based on a irl equivalent), the 83 step verification would be useable 1-3 times per turn (idk how long and significant a turn is) and would allow for the player to automatically know if the person they are manually verifying is more likely to be trustworthy or not.
2. I would increase the 'sillyness level' by a small but not insignificant % - what Im thinking of the sillyness level, possibly renamed to something else in the future, is that the higher it is the faster the userbase and activity grow but also stability decreases and there is a higher chance of random negative events firing, and if the sillyness level reaches 100% then its essentially game over with the server/wiki becoming ungovernable, and if the sillyness level reaches 0% the server/wiki becomes inactive and dead so it would be a thing to balance for the player, I would for example be a counterweight to Bernhe who I would say would lower the sillyness level drastically as a character (before becoming unavailable halfway through the game).
3. I would boost twitter (x) activity/efficient significantly - havent thought about it much how it would effect the game or what role it would play but I essentially make 90% of the FPCB twitter posts irl
