If someone pays you $300 a month for your posts, then you can really consider yourself lucky. For a few minutes a day and a couple of one-line posts, there is no reason not to like this forum 
There's only one "someone" who pays that amount as a maximum per week as far ask I know, He was talking about $300 a month, not per week. It is clear that the campaign in which the OP participates pays him that amount:
2. Signature campaign: Legendary/Hero - $300/month, max 12 participants...
Hence the comment, I think sarcastic from Lucius.
