Due to my own personal experience, below sites do not pay. Probably, they are scams.
Submitted withdraw payment request, after refreshing the page, the satoshis are back to the account. That means the withdrawal button doesn't work at all. Original min. withdraw amount is 20,000 satoshi, however, when you reached the amount of 20,000 satoshi, the min. withdraw amount raised to 30,000 satoshi. You would never be able to withdraw.
Same as above
You will never get paid. You can't add your Paypal email address at your account, you have to contact the admin. The admin will make use of any excuse to refuse to add your Paypal email to your account, so you can't get paid.
My account has got over sixty thousand satoshis. They diasabled my account. Sumitted support ticket. They finally diabled my support account as well. Contacted the site owner, no reply.
I earned one hundred thousand satoshi on the site. Submitted payment withdraw request, the transaction code generated was fake. No payment received.
