Signature compaign is the easyest way to earn bitcoins. You can create miltiple users and talking nonsense on forum just to build up your rank. When you'll be sr. member and above, you'll earn quite some money. When you'll have 2 bitcoin, go to bitcoin casino, put 2 bitcoins on single bet, and win. Simple 
Talking what??? Nonsense you said???
Not everyone does that dude... People are here to talk and help, so they will do... I don't know what kind of people you are talking about and taking into your criteria...
