This will only be a waste of time, I do agree that there are a lot of ways to earn, instead of wasting any of your time and effort in a faucet, do other things which are way better and the payment is worth it, it is the best of choice. There's a lot of options, bounty campaigns, trading, investing, etc.
Yes you are righr, why do we need to invest our time to those things that aren't worth our time? There are so many things to do do earn for your precious time not just only a cent you will earn, like these bounty campaigns you will earn here and this will not waste your time and effort you will be educated here too.
in my opinion it is not in vain, for example, you do 1 day bounty work for several threads, and some time to get results with a small percentage on a site. I think the work can still be done, which makes people speak unfavorably because of repetitive activities with little results.
