Is this is a joke? You can't join 12 bounty campaigns at a time, you must only join 1 bounty campaign for you to earn bounty, because if you are going to join that many then it would be impossible for you to wear all of that signature codes and you will be disqualified for doing such thing. But if you mean that you joined 12 bounty campaigns one after the other one and you are just now waiting for the distribution of token then it is allowed.
I was really disappointed that this post comes from a Hero member. What I know is all qualified members can join as many bounties as they want except Signature.
Don't be disappointed since his name is same with that word er? Hahaha. Don't look in the rank here in the forum for the post quality and integrity because some of that high rank account is just bought account and used by newbie member. If you go out on global section. You will notice that there so many high rank account that post too much low quality post and shits tho.
This thread must be closed since this was answered multiple times and as a conclusion. Only join on a bounty program that have a good reputation of developer team and also the bounty manager. This will increase the chance for the success rate of bounty program. This will not guarantee but will just help you.
