please do not run any mods on your client that can cause you to have an advantage. I would just say to not and play with ponies on your single player game.

I'm sorry for giving a generic answer as I didn't investigate the mod. I was just following:

You will not install client side mods which let you item spawn, speedhack, flyhack, xrayhack, or cause any server wide changes. This includes abusing the economy/server system in anyway to get an unfair advantage over any other player.

without investigation for that i'm sorry. I know now that we can install MLP mod.

 

...Zeno, did you even look at what it does?
This won't give any advantages, or shouldn't, all it does is change the way you see players, that's it.

 

it will not be blocked all it does it change how things look clientside.
