First order of business: No, this account has not been hacked. The original blogger has simply realized that this dead blog has more reach than anything else they have available. ....Yes, they're sad about that as well. They're also starting to really feel weird about choosing third person for this, and switch away very soon.
Second order of business: This is 1000% a "just trust me bro" signal boost. As far as vetting goes, use your best personal judgment; this is being linked because my relative knows these people and passed the link along to me, and I trust said relative with my life.
Final point: With my various blogs, I usually try to stick very firmly in the fandom space, no matter what the world does. I do this because I believe everyone needs a place that they can escape to.
In that spirit, this family needs a geographical place to escape to desperately. Their suffering doesn't make them any less deserving of peace.
