Yes. Trolls who enjoying causing grief to others for the fun of it. In Ultima I knew a Griefer who would upset players with a chair, a 1 foot square island and a teleport trap.
Set off the trap TP'ed you to a small one foot island with a single chair that you automatically sat in and could not leave due to the small size of the island, while the griefer would sail by in a canoe and laugh at you.
And that's why sitting in chair technology is bad for STO. I suspect that the developer of the tech was playing Ultima a few years ago. He is confronting his nightmares just now!
