I can't recall where I saw it only recently, but isn't
Vispillio a merit source?
Is there a list of such users?
I don't know of a list, but if you look at
his bpip stats you'll see:
Has sent 6344 merit 2712 times, to 502 profiles ( 12.6 merit/profile)
Has earned 1091 merit 582 times, from 135 profiles
And we both know that this kind of stats are possible only if one is merit source.
