I still have a bunch of accounts but it's actually not a friendly site to use. I remember telling friends about it back in the day and they'd try and use the site, then they'd come back and be like "everyone on that site is an asshole." I'd explain it in some dumb way but it's basically true in essence. I even modded some default subs like 10 years ago and it was the first time I started hating the site.
Even hobby subs had these issues. Like the top post in r/synthesizers would be about some youtube personality and people debating about drama. People who post actual music and productive things don't get upvoted. Saying you liked the "wrong" people got you made fun of. Super trend/hype based as well. I posted asking for advice for a product to buy once, and was heavily discouraged from getting what I thought was the right thing, I got it anyway, and now it's basically a meme as the top recommended product for that purpose on that sub.
Basically moved to forums and discord servers for a lot of interests and it's so much better than reddit. Early 2010s was the golden age for the site back when there'd be those reddit meetups and stuff.
It's also so fake, people performing the idea they're successful at the hobby as a sort of feedback loop of validation. Posts about buying a thing or showing their stuff always gets more interest than someone engaging in the hobby, with the exception of influencer types or the upper echelon of aspiration.
Joining other communities... music and car related to be specific, I post a work in progress and get instant feedback and messages from people in the relevant scene to share their process etc. The influencers are in the mix with everyone else and are contributing things everyone can use.
I found it took about 3 months to get bored with a subreddit. That was about how long it took to see the same postings and comments cycling over and over.
