Accounts created from networks that have above average fraud rates or that make it difficult to detect fraud may require additional verification steps. Even after this step, some users and regions may not qualify for rewards.
If this step is required, you will be notified when creating an account or entering the rewards area, which will then walk you through it.
大家都應該有用Tor Browser嘅經驗，噉我喺度再推介一個全程用Tor嘅匿名Linux Tails。
Tails is a live operating system that you can start on almost any computer from a USB stick or a DVD.
It aims at preserving your privacy and anonymity, and helps you to:
use the Internet anonymously and circumvent censorship;
all connections to the Internet are forced to go through the Tor network;
leave no trace on the computer you are using unless you ask it explicitly;
use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging.
你只需要一隻8G以上嘅USB手指，一部用得下嘅電腦，就可以裝Tails。裝好之後用USB boot就得（如果你喺中國或者唔想ISP知道你用緊Tor，可以喺開機嘅時候setup個socks proxy）。
預設情況下，每次reboot你喺Tails入面嘅所有資料會自動清除，如果想保留一部分資料，可以喺入面開encrypted persistent volume。
