He is participating in some signature campaign (I guess) where the quality of the post doesn't matter.
If that's the case I wouldn't blame him, but the campaign manager. Why would he struggle to make quality posts when any crap post is paid just the same?
Here is why he is getting paid:
1) First of all, most of the members here think that only long posts or merited posts will give traffic to those signatures. In reality, other small posts might be ranking in Google and thus giving them sufficient visitors. I am not sure if the campaigns managers are checking traffic brought by each applicant but they must by analyzing returns on the total payment being made.
2) We should also not forget that it is hard to find active members here.I have seen members participating with lot of enthusiasm in beginning but they are not able to even complete minimum posts further.
