"It's not like they're kicking math off of YouTube."

Actually, a funny thing happened to me recently that is sort of in this vein. I made a simple app for tuning theory nerds, for examining how a given equal temperament approximates different whole number ratios. I couldn't link to it when posting on a Facebook group; I was told it violated Facebook community standards (I think they just completely blocked the 1mb.site domain that I hosted it on).
