The feature iself is EULA compliant. You obviously have no idea what are you talking about, start a expansive server and talk to Mojang yourself. When you do, come back and talk to me.
I'm not saying the feature isn't compliant. I find it funny that you have "talked to Mojang about the eula", when servers with 3000 active players didn't. You're either lying or Mojang staff is retarded. Go find a way to make voting compliant and fix up your basic 1st grade spelling and grammar. When you do, come back and talk to me.
XP Withdraw sounds like a great idea but I don't know if I want to implement something like that right now. SilkSpawners - I don't want to add SilkSpawners but perhaps I could add spawners in the rare crates or legendary crate. (We're re-adding legendary crates back to Skyblock and Prison soon as we might have found a way to make them EULA compliant). Mob Catcher, nah. Alts/Voter Parties you can now only connect with two accounts per IP. Merged Mobs - For now, no. I will implement this plugin again when server starts to lag. :p
