This should go without saying. People are getting naked for your viewing pleasure. Also "big" is somewhat subjective so don't be rude because someone's breasts aren't large enough for you. If you don't have anything nice to say, don't say anything at all.
Please provide a minimum of three(3) photographs with your username, the date and /r/BigBoobsGonewild hand written in the photo. If already verified else where, simply repost the link with [Verification] in the title. Verification does not require showing your face.
Don't try to pass off someone else's photos as your own. We don't want to have to be strict about verification but if it's questionable, expect to be asked.
