I doubt whether it is icodrop. but diffidently not icobountyhunt.com. He has said that trusted bounty campaigns indicates in green something like that. My bad I can't remember properly .
By the way How are these sites ?
Those are only list of ICO's so its up to you if you will join or not with those. I can't help you out with that sort of thing if it shows something like a green indicator, I haven't seen like that before.
bountyhive is the most user friendly bounty platform so far I have seen.
It has a very active advertising here in forum and I went through the platform itself and it looks clean and helpful for bounty hunters.
Yes I agree with you, Platform is maintained by Colourless. Good bounty manager.
