Mod on the server

Hey Guys Spark here! Well I really want the Smart Movement mod, but i don't know if I would be allowed to have it on the server. I saw a video on it and if you climb on iron bars you get kicked for flying. If the mod is allowed, I was wondering if there is anything to do about the flying thing. If you guys find anything about the situation please post!
From, Spark

We have a lot of server stuff to deal with right now so for now just refrain from using those smart movements. We will discuss it when we have time to consider it but we probably won't be getting it.

The Smart Moving Mod allows players to climb fences and walls to get past player built protections for their crops and animals. This could potentially lead to quite a bit of greifing, since animals could be destroyed without being able to see who did it, this Mod is not allowed in the server.
We will be adding a plugin that will either block you from joining the server if you have this mod installed or block the use of this mod in the server.
Feel free to use this mod in your single player game, but not in the server.
