Op never stated that he is against gambling or mixer services. I think he is specifying the kind of service he currently wouldn't want to promote and he has the right to choose the product or service he want to promote.              I also understand that @UchihaSarada is not really insinuating that OP is against gambling and mixers but he was just recommending these two projects to OP because they are neither related to mixers nor gambling. But @UchihaSarada didn't choose the right word because that word 'against' is not appropriate.
However, I wish @OmegaStarScream good luck in his quest to get a deserving and suitable contract.
