I do not entirely know. Usually, the approvals are about posts or new accounts that are questionably spam. For them, it at least mentions e-mails being blacklisted, and the like. For you, it is just giving us the posts.
Did you recently change where you were posting from?
There are 2 computers I regularly post from - and since I'm working from home now, both are readily available to me. One's my home computer (and linked iPad), the other is a work computer with a VPN connection. I may have had an active login going on both so I may have shown up with 2 IP addresses? Maybe?
We were just asking the same question in the mod forum. We don't know why your posts keep appearing in the approval queue the last few days. Some algorithm somewhere thinks you might be a spammer all of a sudden, but I can't imagine why it would think that.
I think I’ve found it. It’s the old legacy copper community supporter accounts. There’s a few people still in that user group, though it no longer exists since the new CSA accounts were introduced.
