I think if this were to happen it should be a weekly event.
Bids are cast one week and then the winner gets his slave for the next bidding day and so forth. So that there is only ever 52 slave days a year.
Also No Moderator, Admin, or EC member can be picked consecutively. Like you can't pick Creepy one week and then pick him again the next week.
Otherwise the Mods and Admins would not have time for anything except being slaves.
And also the time should be based on the amount of money bid.
Like 10k per minute, thus someone bidding 100k would get 10 minutes and someone bidding 1m would get 100 minutes (1 hr and 40 minutes). Of course it could be more or less, I'm sure the EC could figure it out.
And before the winner got the slave they had to show the slave the money ahead of time, so that the slave didn't get scammed.
Just a few ideas I thought might be worth considering if y'all do do this.
