Great site, used for sharing links and discussing them. Also has pictures on. Things aren't suitable for younger viewers are almost always labelled as "NSFW" literally standing for "Not Safe For Work".  The website is made up of "subreddits" which are essentially Facebook Groups on steroids; anyone can make a community about anything ranging from cute animal pictures (/r/aww) to CS:GO trading (/r/GlobalOffensiveTrade). Some subreddits are private, and you must be invited to join, whereas most are public.  Similar to "likes" on other websites, you receive "karma" on Reddit. People tend to love karma, and many will do anything to get a high score. Just be aware of that as you may see some people who repost and repost to rack up karma. There are also lots of inside jokes specific to the website; if you are unsure what a reference means however, /r/OutOfTheLoop has you covered.

Admins of site have lied to users frequently about their views on 'welcome' content and frequently delete posts that disagree with them. In addition to this, many moderators on this site will ban users for what are rather innocuous comments, or for disagreements, or for the crime of posting to a forum they disagree with. Overall, this site is controlled  by liars, and I would NOT recommend making an account on this site.

Overall a very good site. It can have NSFW content, but only in certain subreddits. NSFW content is marked with the [NSFW] tag, so it's usually pretty easy to avoid.

This site has a natural tendency to create an echo chamber. The selection of what should be 'quarantined' also doesn't seem to follow their TOS, but rather, the political agendas and opinions of the moderators. I have rated it as suspicious for these reasons.

The users of Reddit are predominantly civil and okay for children, but there is a tremendous amount of pornography, racism, violence and other adult content in the various parts of the site. Parents should be very careful about allowing access to Reddit to children.
