With its decentralised structure, community moderation, and hands-off management, it's hard to generalise about the social network Reddit. The site is built of thousands of 'subreddits' - user-created forums with a focus on specific topics such as the video game Destiny, fitness, a love of maps, or even just drugs.

But each subreddit has different norms, rules and tone, which can make navigating the site an exercise in frustration and nasty surprises. It takes a while to develop a feeling for any particular sub, by which point a hostile community may already have ruined your day.
