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.
If my memory strikes correct then he was a merit source but later it was revoked. Don't count on me, I could be mixing him with someone else too.
