Few days ago someone said reddit is mostly bots and when I said I went and checked the profiles of 10 different top commentors from the most popular subs and said that none of them seemed like bots to me I was then essentially told that they mimic real humans so well that it's impossible to tell.
So in other words it's not actually mostly bots but this is just a narrative the people hating on reddit want to believe in. If it was actually mostly bots it would be easy to verify by opening 3 random profiles. Atleast one of those should be a bot.
