Hey there, the somewhat oldish/newish EULA states that you cannot sell in game currency or items that can benefit the payer over non-payers.
I'd like some clarification about this.
If you haven't heard Mojang is blacklisting servers who aren't following the EULA, EULA is an agreement that prohibits servers from having a Play to Win server, Purchasing a rank and having enhancement to gain unfair advantages to win every game is against the EULA agreement, This doesn't...
I found this video, talking about some Minecraft EULA announcements.
Not saying that the server particularly goes against this. But you may want to take a look anyway.
