No. That'd be way too messy. All of the different coloured names in the 'online' box will just look disgusting.
Besides, in the "Members Online Now" box, staff or not, they're the tacky default blue. So the online box would be fine
My suggestion is that the report section should be submission only. It should only accessible to the Minetime staff only. It's to ensure who ever is reporting another player won't be targeted by the player, or friends of them. Also, when players know that they are online, they'll filter themselves until they are offline. Now if we have a submission only report section, not only they won't know who reported them, they'll filter themselves regardless who's online or offline.
I agree, some are amusing, but the main reason of player reports is to report players who break the rules. Just a suggestion of mine though.
