There´s a lot of people that received double payment, there´s gonna be a lot of people that does not gonna receive their payment 
Yes, there have been cases where double payments happened. It's not our fault, the transaction was sent just once, the ETH network processed it twice.
This doesn't mean someone is not going to receive their bounty because of this. We pulled funds to cover for this from the authors reserve fund, as everyone can see.
Please lets keep speculations away.
Also, since I've seen a couple more:
"I use a yahoo email address, there is problem with yahoo emails". - Not true.
"I use dash - in email address, there is a problem with dashes" - Not true
"I am from Vietnam/Nigeria, they blocked these countries" - Not true.
PS: We've also receive dozens of email threatening to post negative reviews in here if we don't pay them tokens in exchange; from people who didn't even participated to the bounty campaign. Needles to say we refused.
Thank you
