Are you sure or just a guess? I do not see any of them confirming that they have received the coin since they made their withdrawals this month
I think 2 weeks is the fastest time for them to receive coin.
Bounty withdrawals are checked manually to avoid sending coins to bots and/or multiaccount holders.
Now that we are at the exchange many people decided to withdraw, but they didn't check that this process needs time. So now we have a large queue and send coins as soon as we can after the check.
