My 2 cents ... I bet that FatFork's answer was more appropriate than yours, since his message is "on the topic" with the only difference that he added a small comment, while your rebuke is already creating a flood.

Now for 777 campaign, we all know how old it is and the structure of payments there. People joining there know well what they are doing so personally I will not criticise the campaign.
