A non-trivial number of the newer accounts that do that are bots, ban-dodgers building karma, people aging accounts for general resale and so on. Even a lot of "human" activity on Reddit isn't in good faith before you even get to the general triviality 99.9999% of it represents.

Plus at this point if you really want to ask what Reddit thinks ask an LLM, it'll tell you in painful detail without exposing you to that place. Just remember to check claims and sources (a good practice for human claims as well as LLM ones).
