I've had a couple of articles hit both. r/programming is a traffic machine because it has a huge readership, not many articles, so stuff sticks around for ages.
I think www.writemoretests.com is blacklisted at r/programming though, which is a shame. Either I asked coworkers to upvote my stories too frequently, or someone took offense to my articles. Meh.
You can message the moderators and ask them why is your domain banned.
I did for my own blog and the response was that I got automatically flagged because lately I was only submitting links from a single source. One moderator then un-flagged my domain, but this means that if I don't submit links from other sources as well, I'll get banned again.
