Most of the bounty managers have their website in which they upload the bounties in which they manage and make it easy for the hunters to find the bounties they manage and easy accessible for hunters. But these managers don't do upload spreadsheet for hunters to see their stakes.
The bounty managers on Bitcointalk always have their spreadsheet shown to hunters and make them awear of the qualified people and the rejected hunters , but to find the bounty of some favourite bounty managers is not that easy.
Instead of you taking unnecessary risk, its better for you that you just stick to what you know is right. Since you already know that bitcointalk bounties seems more safe, I dont see any need for you to go for what youre not sure of its safety. Oh, and btw there are even some that are not safe on bitcointalk, not to talk of those that has their own website and has no spreadsheet.
Just go for what youre sure of so that you just dont waste your time and internet connection all for nothing because I do see many people are planning good but later-on do spend lots of time on social media and finally achieving nothing.
