I'm pretty sure it's a thing already
Just send an admin 1 billion TC.
Link is right I'd say. It'd be pretty hard to distinguish staff from non-staff if it came down to it.
Though I'm sure if the right jimmies were rustled and a nice amount of TC was offered, this would be another great way to sink TC. However we have ToriLegends now, with that good 'old gold' colour for their usernames
I don't see this happening because of how staff and members of significance are currently recognised. I feel that most other alterations, with the exception of colour, are plausible.
