Black screen with the text "Website Blocked by Filter"?

I think you've got parental controls at work here. You won't be able to undo them without access to the account that set them up. As a parent, however, I will tell you that blocking software can have a mind of it's own and block sites regardless of them being set to "safe". I had terrible issues with allowing my kid's gaming sites (like Neopets, etc.) when they were young. He might be frustrated with other stuff and this is just one more thing on his plate. Maybe ask if you can sit down with him and try to figure it out together and explain why you want to be on tumblr and why it's not a dangerous site. Good luck!
