1. Ruminisque.
2. xFritHD.
3. Illegal Modification. (Toggle-able Sprint)

For reference:

Not Allowed:
Mods that give you an advantage over the other player.
Mods that assist you in PvP fights/Building scripts.
Mods that come in a form of hacked clients e.g Killaura, Anti-KB, Tracers.
Glitching items/into places isn't allowed.
Duplicating items.

Proof:

 

ToggleSprint, or in general the BetterSprinting mod is allowed on the server. The owners feel it does not give players an advantage. This has been challenged several times now to be changed, but no change of mind has come.
