Pretty sure they prevent new accounts posts from showing up as often as others, or just straight up hide posts from new accounts these days. Especially if you signed up with proton mailz or in the web browser, vs linking your google play login to the app on a phone that's not already flagged.

You have to try really hard to farm karma on new accounts and on my old account I could reply with simple one word response and still somehow get 4 upvotes. And I didn't have followers or was a big figure people would remember the name of or anything. It feels like after a set time and a certain amount of karma you start showing up more.

I think they're very insecure about ai coming in and ruining the training data they are trying to sell so they really put up lots of walls to ensure its "clean"

Back in the day you used to buy bulk emails that where leaked and many of then where throw aways and occasionally they had a reddit account attached to them. But google deletes inactive emails now, and all new gmail account are 2 step with required phone number. So I think we are just getting locked out now.
