Recently? Do you have the link? I guess they are saying if the admin approves it then it will show.

Reddit has at least two Steemit sections. I am not that familiar with Reddit so there might be more.

First section ( sub reddit ) is called Steemit
https://www.reddit.com/r/steemit/

The second sub reddit is called Steem
https://www.reddit.com/r/steem/

Have you tried any Steemit links in a general reddit section?

No, I don't post on Reddit often. I got banned from allot of the sub sections when I was spamming affiliate links ! To be fair I didn't read the Reddit rules and just posted what I wanted until my eventual ban from many different sections of the platform.
