No, I absolutely loathe it.
Because it always, always, turns into a game of "paying players versus site owners mates", where you get slotted over and over and over again by some chuckleheads that you think are marshals, but are actually untagged players who are enjoying an entirely different set of rules than everybody else.
You can dress it up with any meta that you like, but this is what actually happens, every time.
I hope this has been helpful to you, and that you won't just "yeahbut, my special rules are more specialier than everybody else's special rules."
Shock me, say something other than "yeahbut".
[UPDATE]
Are you shilling this "tracker" device.
