Comment.

Share your knowledge, experience, humour.

Do not post 'posts' / links.

You don't need to concentrate your attention anywhere in particular or to explore anything in depth. I stay away from news / politics / gaming subs even though they are my main interest until I have enough of a history / karma.

Some subs do have subreddit specific karma limits but they are many and varied.

It can be a long game, but gaming reddit with comments is easy enough so you'll pass their 'checks'.

Shows up as a brand-new user, opens by posting a link to a low-effort blog post, gets bounced.

Sounds like Reddit working as designed, TBH
