How do I get passed being blocked on finding information out on my husband on the internet?

Answer 1

You could always try to access his social media accounts through other family or friends on there - if you are friends with them.
Other information might be privileged and you may not be able to access without a court order.
Really you should be able to talk with him about this. Why do you want to do so and why he blocked you would be a good place to start the conversation.

Answer 2

Depends on what it is. Different sites have different information and security measures. I'd first question if YOU are the one blocked (and why), or if it's privileged legal information you're trying to access.
