It didn't work in Runes of Magic, which I played briefly. In fact the opposite - since farmed gold could be traded for 'valuable' shop items, some zones were 100% bots.
I think the STO dilithium kind of solved the issue - there are no dilithium farmers in STO AFAIK.
On the other hand, RoM allowed you to buy reallly powerful stuff that affected PvP, so I cared more.
