So I guess every reaction and review on the internet that is ad supported or behind a payroll is theft too?

LPT: if your dog is being playful and you need to catch them, try running away to have them chase and catch you.

My guess,

1. It was too hard to create a non-authenticated algorithm which could let users delete their past participation.
2. They realized their non-auth algorithm was exposing too much info about what is going on during the upcoming election. And they are afraid that people will see all the fasc recommendations.
