My IG photog account was suspended this morning, but they wouldn't specify why. The only things "wrong" I did that I could think of was block accounts of large brands who had ads in my feed and have "Now posting to Pixelfed!" in my bio.
I was able to get it back online after appealing and doing the whole "look left, look right, look up" video selfie. They apologized in the email, but still didn't say what they thought was wrong.
