Yall should allow people to add their own plugins, I got so many plugins that I would want on a server that I cant put them all in the forum. Not only would this stop the plugin recommendation spam, it would lead to a lot more diversity and creativity in types of player servers.
The staff has to tell people time and time again that it's a security risk. They will never add this feature due to the fact that there are Java developers out there who know how to work with bungeecoord and are able to do commands from the plugin that they designed themselves that could op them on the network or ban everyone or do whatever they want, and the worst part is there is a small chance that we would find out unless he was recorded with operator permissions. And this is also why they have to review the plugins before putting them in, as to not destroy their network.
