Hey, thanks for feedback. I also confirmed I couldn't be muted or blacklisted, because I was wrong, it's not all my posts, my HPUD post yesterday is visible on Archon website. So tag or maybe other community incompatibility sounds more probable. BTW, I wasn't complaining about "excluded tags", of course every community can choose which ones they want to exclude. I was just asking if maybe there were more than the ones I listed (found with scot.api). The post that really made me wonder why it didn't appear in archon was posted in the hivepets community. It was not related to any of the photos contests Archon promotes, but it did includes lots of photos, and overall I thought the archon tag was okay for this one (of course I never add the archon tag for my Actifit posts for instance). It was this one: https://peakd.com/hive-196708/@manuvert/kaia-and-the-simple-joy, maybe you can find more info there.
Thanks, and have a great day!
