We seem them all over the place on my server late at night just teleporting and farming stuff in some of the smaller zones. I've reported it when I was a sprout thinking it makes a difference, and maybe it does but there is so much of it nowadays you just leave it alone.

Whoever is doing it will keep doing it, since they just need to create free accounts. I wish that SqEnix made accounts be tied to a financial payment or something even on the F2Ps that get refunded if you don't like it, cause at least then you can track the RMT accounts.
