Never share them to anyone, Save it somewhere that you will surely remember.

I'll recommend this thread for those newbie bounty hunters, it seems legit plus the bounty manager was a friend of our previous bounty manager where we joined as a newbie for a signature campaign. And the project was a huge success and we earned fair enough from it. But don't forget to post a quality post and follow the rules. Enjoy your 1st bounty campaign.
