The upvote system is also basically useless on reddit these days, the site is way too big to enforce any kind of etiquette and people gladly upvote empty one-line quips while they'll bury anybody expressing any form of vaguely dissenting opinion. It's frankly toxic.
At least good old blog spam is easy to identify and ignore.
There are a few topics I care about where you have both big subreddits and also dedicated "old school" forums on third-party websites. The forums are always more interesting and in-depth in my experience, when the subreddits are just a litany of karma-whoring picture posts and low effort so-called "memes".
