It's not only about being lazy, but it's about not being knowledgeable enough to do that. Someone whose primary purpose of joining the forum is to earn money will hardly have enough knowledge to make any good posts or take part in discussions with constructive and useful responses, all they can do is either hunt bounties or farm and sell accounts.

I'm not saying that OP is one of them, but I'm just explaining a certain category of people and how they behave after joining the forum. Those with potential to gain Merits and rank up are the ones who are serious about learning and not only here to join signature campaigns or bounties to earn money.
