If Lemmy and Mastodon continues to get popular, we will eventually get Instance wars.
If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that's for the future of us all.
Each participating instance must choose a "side" from a selection of political systems, religions, world views, etc. whose views it (the instance) has to represent.
The war takes place in a community that is unlocked for all instances, or on a separate instance.
All instances are listed and numbered.
The opponent allocation is then done by a /random bot number generator.
The evaluation is then done by a /Poll of all instances.
The loser is kicked out and the new opponent for the winning instance is chosen again by /random bot.
