this almost killed /r/indianfood. we had to clamp down very sharply on posts that were just links to youtube videos, even if those videos were technically on topic for the sub, not out of any desire for petty power tripping, but because the page had literally become a wasteland of youtube spam crowding out other content. since then things have gotten a lot better, and we even get a drive by comment every now and then thanking us for sticking to the rule.
