I think you need to understand the working mechanism of this forum. Unlike BTT that uses the merit-base system for ranking and also signifying quality post, the ATT uses post count for ranking, and Karma for signifying quality of a post. I don't think teleported users or even native users should be bothered, because with just a single +karma, one can also issue out countless numbers of karma to others within a specific time frame.
In another sense, it would make more sense to rank up on both platforms at the same time, rather than focusing on ranking up on just one without affecting the other.
