Based on my knowledge, it will eventually die. Literally 100% of all the player servers I played during all these years have died. The only thing that did not die was Warzone, and thats because it has been revived like 5 times now lol. I don't think Warzone even counts as a player server to begin with xD
A more interesting question would be "how long will it last?".
It depends on how much will it take to one of these things happen:
A staff member abuses and breaks all the server.
A random player from minehut abuses some stupid bug and gets access to OP, destroying the server.
Staff members become less active, and the player number starts decreasing until everyone stops playing it.
The owner decides to delete the server (most likely to happen if the owner is RyanDxxx, FREAKIN RYAN)
The owner quits minehut, starting a process of decay and no evolution on the server.
Minehut breaks, and all server gets reseted (this one has been the biggest server killer since ever. Don't believe them when they tell you it wont happen in the future, because it will, their fault or not).
Community becomes toxic, and people start leaving.
Minehut dies (And now you're like lol this aint happening. It actually happened once, during summer of 2016. Don't think it wont happen, because it may very well happen).
Backups may save a server, but most of the times it wont because of one of these things
Backup plugin doesn't work.
The owner does not has backup.
The owner is too lazy to start over.
And it is mostly the last item that ends happening.
Now I might get comments like lmao Gam ur stupid dumb idiot ofc it will last forever, it is the best player server since ever lol get lost.
Ill guarrantee you: After 6 months, it wont exist, unless it gets revived just like Skyblocksminer was (That server got revived like 3 times and now it is dead. If thats not a good example of how eventually lift will die idk what else of an example I can give you lol).
Now @MikeTheAngel I am waiting for your Sumo 2, @Faacto I am waiting for the OGs do revive beans for the 4th time, @RyanDxxx I am waiting for LegendsRPG or whatever the name was to be brought back, @Draconium I am wainting for Miners, @Kagaroo I am waiting for Cookieclicker, @Gaminger I am wainting for Runners 2, ...
