Reddit's structure is communities (subreddits) rather than feeds-of-people. Most subreddits are wholesome — gaming, hobbies, music, sports, cooking. Some are not. Age-gating exists in name only.
Two specific concerns: NSFW content is gated by a single click that asks “are you over 18?” with no actual verification, and “advice” subreddits aimed at teens are often full of adults giving advice they should not be giving.
The settings that matter
Doing four of these is meaningfully better than reading twenty things and doing none.
Make the profile private from search engines.
Settings → Privacy → Hide my profile from search engines. Reddit usernames are durable; old posts can resurface years later.
Disable chat and DMs from non-friends.
Settings → Privacy → Chat → “Nobody” or “Approved users.” Reddit DMs are a major spam and grooming vector.
Turn on the NSFW filter and hide adult content.
Settings → Account → Manage NSFW content. The filter is honor-system, but it is better than nothing.
Block subreddits as a family.
If specific subreddits are a problem, block them at the account level. The block applies to the feed and to search results.
Set up two-factor authentication.
Settings → Account → Two-factor. Reddit account takeovers are common; 2FA shuts most of them down.
Worth knowing about Reddit
- Reddit is one of the few major platforms where users are mostly anonymous. That is a feature for free speech and a vulnerability for kids — there is no profile photo or bio to evaluate, just a username and a karma score.
- Some “advice” subreddits aimed at teens — relationship advice, mental health, body image — are populated by adults whose advice ranges from helpful to harmful. The vetting parents do for in-person friends does not translate here.
- Karma — Reddit's score system — incentivizes oversharing. A teen looking for validation can post personal details to a sympathetic subreddit and get hundreds of upvotes within hours.
