I’m not seeing this post (only the old one).
I noticed that as well, not sure what’s going on. It shows on my user page o.O
That generally means it’s in spam. (likely because you’re using an account with no karma and you crossed a posting threshold)
Curious, as I’ve not posted anything in a week -_-
Edit: …and I’ve made a whopping 3 posts so far. Weaksauce.
Edit 2: …and for some reason it says the other post is 6 days old despite being posted on 22 Aug. I wonder if it’s because I posted it in the evening rather than the afternoon?
