Hey guys... So, the reason that BSM is still bannable, is due to the fact that Better Sprint Mod has many other features than just the sprint button. One for example, is the ability to sprint full speed backwards and to the sides. Another, is the ability to fly faster, and to disable the double tapping of W. Using the 1.7 sprint is fully supported, and we advise you use it, if you feel you wish. IF there is a mod that fixes the sprint without providing any other features above the basic in vanilla, it would be allowed. Due to what BSM turns out to be in the future, and how it interacts with multiplayer, will be determined when it is released and the officiality of supporting and overturning that rule will be discussed among the staff. Its interesting to see the amount of support that BSM has here, but will still remain against the rules until a decision is come to by the staff... Thanks for reading this, and have a wonderful day!
