Question Boosting using blocks vs fly.

It's possible in NCP (or other anticheat plugin, tell me which one) to block fly, but dont block boosting using blocks?

Boosting using blocks - Change ur Y position using blocks in protected area (so u can get on spawn for example)

(for example, If u falling in protected area, U can place slimeblock while falling under u and it will boost u normally, but disappear after very quick time, so other players cant see this block)
