Well imgur does contain a significant amount of porn, probably more so than most image hosting sites. Probably why it happened, I know some schools block it too. On the plus side, the next version of OF does a bit of trickery where the server pulls in images from other sites that are linked and re-serves them itself. Its meant to help us serve consistent image sizes and apply scaling to fit devices used but it doubles as a way to get around this sort of blocking.
We actually finished off that feature 3 days ago and it works really nicely, no more people linking 3000px wide images that make your ipad / slow internet cry, just fetched by our server from the third party site, scaled to sane dimensions, compressed and served by our servers and CDN.
Bit of a ways off on OF3 yet but we're working on it.
