Buying, waiting and then selling bitcoins is the best way to make a good kind of profit.
Faucets etc are to taking too much time and you earn not enough to actually have some real bitcoin.
Well faucets can be done during your idle time. Rather than posting some bad comments or post in the social media i would just go with faucets
How about posting on this forum instead on some social medias? It will be way more better since you are on a sig campaign where your posts were monetized. Using faucets, even on your idle time, is still a waste of time unless you are having fun claiming little satoshis.
