A bounty manager in one telegram group was mad at the bad English of some hunters and made a statement that his next bounties will require English proficiency certificate. What are your views.I think it will enhance posts quality .
English proficiency certificates will help enhance post quality but I think it is pretty unfair for the bounty hunters that are only speaking native or local languages. Maybe every project team has to include local board posting within the bounty program as it can also help the project be known, spread it's ideas and be understood and promoted locally by local bounty hunters. Based on my observation some bounties requires "English only" language for the program where bounty hunters also has no assurance that the project will become successful, gonna be paying, scam or token payments could have a better value as expected after the bounty program but yeah as a bounty hunter everything is 50/50 so much better to expect the unexpected.
Then their will have a limited number of participants.
