Do you mind joining a bounty program without a trusted manager?
I myself stopped joining bounty programs that run by the owner of the project or an unknown person (you will see them as newbie copper member or Jr. Copper). Due to the rise of high scams of ICO's and I'm not good at finding them I have to depend on experts. I believe a trustworthy manager won't run a shit campaign. So, to stay safe side I choose to join only bounties that run by a good manager or escrowed by someone that whole community can trust. I just don't want to waste my time.

Here is a short list of bounty managers I worked with and liked:
1. needmoney
2. yahoo62278
3. deadley
4. Sylon
5. irfan_pak10
6. Woshib
7. hua_hui
8. MadZ

Note: This is a personalized list with my own experience.

Let me know what do you think about joining in new managers bounty? (New means, newbie copper/Jr. members).

You can find more managers name at this thread https://bitcointalk.org/index.php?topic=3085997 (found this few weeks earlier).
