Yes seriously and Much Respect for the one who did that. You can't say for sure that OP is the one paying for the ad slot (even it's highly likely) but it's definitely someone affected by this incident and wants to draw as much attention as possible on this discussion (to warn people? to defeat the reputation of ChangeNow.io? - who knows really). By doing he/she also contributes to the forum which is not bad at all.
But I admit, it's my very first time to see a such advertising  - It will surely inspire other potential advertisers
