The speed hack itself, just for the movement, was always safe.
Trove (made by Trion) has a retarded and an aggressive cheat blocker. Welp, people are still able to speed up their movement by 5 or 20. Still having an active, unpunished MR150+ account (approx 1 1/2 years used).
And there is no difference for BnS. Aion and Lineage2 were hackable, no one I know got banned for it. Just assure yourself that GG has been killed.
