In 2015, faucets are not bad but 100% DEAD for bitcoin
Nope, as someone mentioned, beginners benefit by getting some free satoshi to play with, plus people living in Africa will benefit too. They will big time too from sig campaigns, given their english is competent.
there are signature campaigns for newbies that pay 1k satoshi/post or so.
How long would take to faucet 1k Satoshi(I guess more than the time required to write 1 post)
Not that low! Maybe 100 satoshis per post, and those campaigns were very evident in 2014. Idk if there are still campaigns accepting newbies that offer better incentives than those of existing faucets.
There's not, because people would just create new accounts, spam until they get caught/banned, put the money they earned aside, and repeat the process. Not to mention newbies are really limited on signatures, which kills the flair.
