Most of the time it is indeed.
I was thinking if someone uses a strategy to comment a full day (8 hours) to earn an income then this is quite alright. Since they put a lot of effort in it.

Only if they start writing tactical comments based on the title, without reading then I still think it's really quickly earned money.

Anyways if you live in Africa, have free internet (for a fixed amount per month) you can easily earn a decent income with commenting. Quite a miracle that not half Africa is doing so.
