From the dashboard, a Tumblr user has the ability to upload text, photos, quotes, links, music, and videos, just as they say, but what most people do on Tumblr is simply reblog pictures they like. Next to the reblog button there’s also a like button. Pictures that are reblogged appear immediately on the dash of everyone who has followed the person reblogging it. If a Tumblr user hits the “like” button, the original poster receives a small message on their dash indicating that a person has liked their picture. You have the option to like it or reblog it”¦ and that’s it. You cannot flag a picture for inappropriate content. You cannot block a picture or content that you find offensive. Your only option is to unfollow the person that posted it. Once you unfollow a person, all of their pictures/content will immediately disappear from your dash, but they will still remain on the site, exposing other users to the content.

• Why doesn’t Tumblr have a disclaimer screen that comes up when a person follows a blog warning them that the blog contains adult sexual content? It seems like a fairly simple safeguard measure to implement. Such a filter would allow parents to screen who their children follow on Tumblr and may deter teens from viewing adult content. At the very least, it would afford teens who are mature enough the opportunity to screen themselves.
• Tumblr relies on the user to mark the content they share as NSFW (Not suitable for work) which would then be blocked by their “filter.” Users rarely take the time to mark the content as NFSW and therefore will not be picked up by the filter. In addition, Tumblr doesn’t allow for those exposed to such content to easily report it.
• If anyone you are following on Tumblr reblogs pornographic and abusive images, even if you have NSFW filter enabled, it will still show up on your dashboard.
