9GAG lets users scroll endlessly through memes, short videos, or plain images or register with an email address for the privilege of commenting on images or uploading (or linking to) their own. Uploads let users add titles and assign two of nine categories: NSFW (not safe for work), Meme, Cosplay, WTF, Cute, Food, Geeky, Comic, and Girl. Users can upvote or downvote images or report content, although there are no guidelines for reporting. Sexual topics are most likely to be encountered in the NSFW category but can pop up just as easily in Hot, Trending, or Fresh. Users can share content they like on Facebook, Twitter, Google+, Pinterest, or email.
