Where does e621 come from? knowyourmeme.com E621 first referred to monosodium glutamate, or MSG, years before it meant related to furries. MSG is a flavor enhancer found in many foods. E621 is what’s known as the E number (a standardized code for substances in Europe) for MSG. The website e621.net launched in February 2007. While it’s not confirmed, it may have been intentional that the board shares a name with MSG, indirectly calling the site and its content tasty. Its counterpart, e926 shares a name with the E number for a bleaching agent, chlorine dioxide, which could be a reference to figurative eye bleach to mentally remove what one has seen on e621. As of 2017, e621 has overtaken other furry specific sites in popularity. In fact, it’s an even more popular search term than the more general furry porn. This is probably because literally anyone can view its archive of sexual artwork without registering for an account, whereas other sites require registration. People who don’t consider themselves furries might also wander onto the site, since it provides an outlet for many hardcore fetishes. The site has been shut down a few times. A couple of these had to do with the fact that it’s been known to host drawn pornography of child cartoon characters. Examples of e621 “He live tweeted his deep dive into e621.
