The fact that people want to earn more money, this is not surprising. If they take jobs more than they can afford to finish, they can always adjust their workload, I do not see anything wrong with that. Everyone has his own problems and his life circumstances. Of course, a large amount of work should not be at the expense of its quality. If the quality of messages remains good, then this is permissible.
I often see couple of people here, who after applying and accepted to participate in a bounty campaign, but never got to perform their tasks. That must be a clear case of biting more than they can afford to chew, because obviously they need the money, but they lack the time!
Simply just like the OP said, I guess they must have bitten more than they can chew! A lot of people do not understand in life the fact of, it is better for you to concentrate on the quality ones and get the best from it, than just pack a whole lot than you can handle and at the same time still get so little from them.
I do not understand how some people think when it comes to making the best use of their time and resources anyway, but I guess probably the way they see things. Trading is much easier compared to investing all we have into altcoins. I never agree on this. We must risk only some 10% to 25% of our total saving. This is based on only that much percentage of saving is affordable for anyone on the event of losses.
