Hi,

I'm the owner of Bitcoinker 
We did indeed reduce the claim amounts a few days ago, due to the Bitcoin price increase. Once Bitcoin has stabilized at a new price point, we adjust the claim amounts accordingly. Also, keep in mind that there are much larger claim amounts in our faucet as well that fewer users get, and that raises the average claim amount as well, even though you might not get those higher claims and therefore see it in your average.
Regarding the minimum threshold, we may lower it in the future once we stabilize the faucet, as currently the Bitcoin price increase has caused us to take Bitcoins out of our own pockets to cover the payouts.

Hi,

I'm the owner of Bitcoinker. The issue you are having has nothing to do with your account, the referrer spam blocker blocks access to the website from autosurf or traffic exchange websites (advertisers don't like the traffic from those sites so we block it in order to not get banned ourselves).
Try accessing the website directly from the URL bar of a new window.

We are one of the highest paying faucets and we haven't missed any payments.

Let me know if you can access the website or if you have any other problems you can leave a comment on the website,
Thanks
