But if they found that you are using almost alt accounts for your bounty campaign they never give you the bounty rewards.
I did not understand this point, why they never give me the bounty rewards, please explain this to avoid it.
Since you are a newbie ranked member, it would be difficult for you to find a bounty campaign but as you level up to a jr.member you might score some campaigns.
But I will advise you to do a research on the project whose bounty campaign you are going to take part in. Most projects tend to scam these days.
