Of course there are several methods to write a teleporting tool. However, none of them can pass validation check.
I might tell you that the validation is as simple as checking how much you moved further at a given time.
You might think that such spells like Charge or Sprint might trigger false alarms, but that's not a case, since the validation process knows when a player is sprinting or charging.
For example teleporting from one map to another is detected instantly if the game server does not expect such movement. This applies to every form of teleportation - thus it's really hard (read impossible) to bypass or avoid it by any action.
