We know that there are micro wallets such as ePay.info and Xapo.com†. But I found a website called
PurseFaucets, which has many features a micro wallet has, ex: Statistics, Earnings history, and Transactions history. It stores users' earnings from its faucets (those faucets all use its script, apparently), but it does not pay users directly, instead, it sends users' earnings to users' micro wallet accounts.
This one's withdraw threshold is 5,000 satoshis. So far, I have only accumulated 270 satoshis on it so I haven't been able to check if it is paying.
Has anyone used it before? Is it paying? And why is there this special payment processor when there are already micro wallets?
† Xapo.com is also a regular wallet.
