I am kicking myself for not having thought of this myself. There's now Anonymous Bounty services. Pay them (and a commission I assume) the bounty and name the target and they'll set the bounty without your name ever coming up. Delightfully enough, I found out through someone putting a ten million bounty on my Jindustrialist, anonymously. Still a tiny sum but at least we're starting to get close to justifying that giant Wanted sign ruining my profile picture.
There's plenty of room below the picture for a Wanted icon/text, no need to smear it across the picture.
Anyway, it would seem the bounty system is starting to become a lot less 'special' than it's previous iteration. Far more useful, but so far it seems to largely be a "lulz, u has bunty no" feature. I am a bit sad that I didn't get mine for IC shenanigans, though. That'd have made it a bit more fun.
