i politely disagree. as another commenter pointed out it depends on the size and overall subreddit visibility.
you can find visible and recognized posters just like you would any online forum in smaller subreddits centered around a thing like writing, programming, music.
check out r/zen for example where there is absolutely an infamous user: ewk and quite a few other regs who engage him in healthy (and perhaps.. toxic, depending on your worldview) discussion(s).
