If they're ignoring GDPR because they're in the US, you can potentially flag these as COPPA violations. COPPA is serious stuff. Courts can fine over $50k for each violation, where each individual impacted can be considered a unique violation. COPPA applies to under 13s, I'm not sure if there are age restrictions in place to join Hack Club, but if there isn't even a privacy policy, I doubt age restrictions are properly enforced.

Hack Club realized this, and now doesn’t allow anyone under the age of 13 to participate in its programs (COPPA doesn’t apply to people over 13).

An 11 year old child's account was promised to be deactivated, went through the dramatic "welp, you had a nice run" text wall, and then absolutely nothing happened.
