Tumblr can be a great place to discover content, share interests, and meet people. However, you might want to block access to it for parental control, or digital wellness. In this article, I will share methods to block Tumblr or just certain content on it.

 

Reasons to block Tumblr

Why would people want to block this platform? There are two common reasons.

  • Protect children from inappropriate content Although Tumblr has banned adult content since 2018, mature or harmful content still exists on this platform. Blocking this platform helps keep your children safe online.
  • Overcome Tumblr addiction Like other popular social media platforms, Tumblr can be addictive. If you find yourself addicted to it, it may be time to stop using it.
