But Faucets are better than investing in Mining equipment and mining BTC, because there is no ROI. But we can get something from Faucets.
If there was no profit in mining no one would mine and obviously that's not the case. Faucets are in no way better than mining, you can do it for free, yes but the profit from faucets is so small you will not even notice it.
I doubt it, there is no way to do that unless you have a bot or you pay to get captchas solved, you end up not profiting in that case anyways. The bots or captcha solvers cost more than what you get from the faucet. If there were people doing that almost all faucets would die.
