Also, whether a merit source is there or not will make no difference to whether I post there or not. If I was a spammer, Little Mouse and Royse777 wouldn't allow me into their campaigns. The truth is, my posts are if anything of higher quality than majority of the other posts in that board.
I agree with you there that you are not a spammer nor a shit poster. You engage in conversation with genuine interest which is why you are able to write in detail. Your posts are constructive. They hired you because of their professionalism. I can guarantee you that even if their known enemies apply in their signature campaign but that user writes good posts, those campaign managers probably accept them because of their professionalism. The problem is in your mind. You are promoting gambling through your signature space while you believe it's unethical. Another point is you cannot take criticism. You jump towards others who write against your point of view.
