Clicking on facets is a horrible waste of time. 0.004 BTC per day is only $1.32 at the current price. That's pretty bad even in countries where the per capita income is only $5 per day.
Yes it is, but it is better than no income. Most of these people are unemployed and receive zero income. If they can pool together and create a referral network, it would turn into something much bigger and possibly passive income in the future.
My kids started this at school and quickly built up a referral network of 500 kids on 5 faucets, doing this daily. They stopped solving Capthas and now get passive income from this, when the other kids use the faucets. This was a very successful project for them.
