Well it IS a teleport, no matter how. But there are still people teleporting without issues, so its still unknown what exactly triggers the ban. Of course its based on teleports, and it can trigger on the very first time if a certain limit is exceeded - see the recent ban wave which hit people because of falling down in the Goemm´s Lab JP in Metrica Province.
But what this limit is, thats the question. Distance? The kind of teleport? Considering it hit people falling down once its unlikely a limit of x teleports per y, where y is the timespan.
Use it carefully and at all costs do not use any teleports on your main account. You´ll pay for it, soon or later, and the bill is salty. Lost my account because of it, got it back because of lucky curcumstances, won´t risk it again.
