The board supports attaching images (.jpeg, .jpg, .png, .bmp, .gif) as well as videos (.webm, .mp4) up to 2,500 kb. Videos can also be embedded directly from youtube.com, vimeo.com, and dailymotion.com.
The point of CyborgChan is a cultural enforcement of anonymous discussion. Any personally distinguishable information that breaks the anonymous character of the board, such as gender revealing ("femanon here"), Discord tag sharing, or tripfagging (using tripcodes as usernames across threads to build notoriety) is discouraged, and will be cleaned up on sight. This is considered a sitewide rule (https://cyborgchan.net/rules.html).
CyborgChan additionally employs vichan's implementation of the original Robot9000 algorithm: making a post that's too similar to previously-posted content will trigger an automatic mute for 2^x seconds, where "x" is 1 + the total amount of previous mutes you've acquired. Unlike 4chan's /r9k/ board, CyborgChan's robot does not ever forget content that's been posted before. It will, however, forget mutes that are over 48 hours old (this puts the maximum possible mute time at just over 36 hours).
Aside from those two caveats, anything that would be allowed on 4chan.org/r9k/ is allowed on /c9k/. Illegal content will be taken down, and I strongly encourage you to report it (checkbox next to post), but this is otherwise a very lightly moderated board.
