I mean don't get me wrong, the payments on signature campaigns are the best ways for casual people to get some BTC compared to the depressing amounts you can get off faucets, but the people that take it as an actual job are missing the point.
You don't know other people's circumstances, therefore you shouldn't speak as if you were preaching the ultimate truth. You should first try walking in their shoes before arriving at such sweeping conclusions bordering on accusations. Also, could you name a signature campaign that pays for posting 30 times a day? If I'm not mistaken, no signature campaign as of now pays for more than 50 posts a week, which roughly equals some 7 posts a day.
