Either all my hashtags work, or none - depending on the day.
If I post and click a hashtag I can see if I'm showing up in the recent posts or not. If one hashtag is not working, none will work for that post. I can delete that post and repost it with new hashtags, or post another photo entirely, but once I've been 'shadowbanned', that's it... done for the day/week/month...
I don't think I am breaking any rules. I also seem to be tame compared to a few of the accounts I follow who are not having this issue.
Anyone else experiencing this?
