US is full of companies that publicly claim to manipulate reddit threads as PR protection. They all do it exactly like you’d expect - people with dozens of phones going through threads writing shit. Even if users are banned and their phone fingerprinted they just dump the phones for new ones.

Reddit knows could actually sue them and very likely to win but that would be a lot of attention at them.

The best part of this is - if commercial PR companies can afford to run this then what China, Russia and such are doing must have absolutely bonkers. There’s very little internet actually left organic.
