#BBC
#bbc is a community tag, and Nudzy does not define it for creators. Because abbreviations mean different things to different people, the best guide is each album's own title and description, which almost always make the intent plain. Treat the page as a collection of whatever the posting adults chose to file under it.

Respect is part of the house rules. Content that demeans people or reduces them to a stereotype is not welcome, and moderators remove material that does. To find a more specific direction, #big is another open-ended label, #pov collects first-person footage, and #cheating holds consensual role-play scenes.
Every person shown must be an adult who agreed both to the recording and to its publication. If an album appears to have been uploaded without that agreement, or uses the tag in an abusive way, you can report it from the album page.
