Problem is Reddit content and votes aren't all human so unless they kept a record of which parts are just chatbots and which votes were faked its not exactly useful to train on in a pure sense.
Considering the disinformation wars and botnets between the big countries its hard to even get a idea of what people really think and what is bullshit and what isn't.
In any case I'm glad reddit has fucked themselves. This small corner of sanity is a bastion in a shit blizzard.
