Curate, connect, and discover
if they want your information they’re feds
I'm sorry but it's way too sketchy to have to "sign up" for a protest. There's no reason you should have to give anyone your full name, email, phone number, and/or address in order to march in the streets. People are getting arrested left and right because cops have access to information that connects people to the protests they were at. If an organization is having people "sign up to join the fight," all the cops need to do is access that list.
Just go. Don't leave a fucking paper trail.
