Solved Community server mods?

Hello, I am trying to find out what type of mods there is that I could add to my community server without having it change to the Modder Server.

Reason why I am trying to find out is because I joined a Community Server a couple days ago and found out they had a few mods in there server. It was strange due to the fact that I thought you could only have mods on a modded server and not in a community server.

Any suggestions which mods I could download??

Thank you!

 

Hello, would adding a mod that increase or decrease the loot chance in my server make it blacklists?

 

Ok, so look for something that adds into the game, but not change the mechanics of the game?
