I Have Been Taking Photos Of People And Putting Them On Youtube Videos In Satirical Context Without Consent. In One Case, It Was Against Their Will. I Do Not Leak Any Information Or Send Hate Or Anything Towards Them. All I Do Is Post Pictures Calling Them Things. Is This Legal?
In the US, there are some contexts where permission is required. First, if you are commercially exploiting a person's image, then permission is required: this is about civil personality rights (which in California are also recognized statutorily). That doesn't seem applicable here. The other is "video voyerism", which is a federal crime, and that is about posting pictures of someone's privates, which I also assume is not applicable here.
