I crossed out those I do not know yet.

Many of btcltigigger's campaigns did not really turn up well for the bounty hunters. I think Vanta and Orbis was the last blow which led to many leaving his/her group. With regards to his/her professionalism and addressing bounty issues, I think s/he's quite alright. Maybe 4/5 rating

Arteezy for me is quite average when dealing with bounty issues.

I only know of Bubbalex from other forums I'm also in. From what I observe, he's strict which is good for me.

There's not much to tell about Hhampuz. Almost everyone knows he's really good.
