I made an account last night and posted to Critique » Pixel Art. I previewed my post a few times then hit "Post" but I'd forgotten to verify that I'm a human. So I went back, verified and hit post again, but then the system told me that I'd already made that post and I probably double-clicked the button.
My post didn't show up on the index, so I tried again 5 minutes later: another duplicate post error.
Was my post auto-quarantined for mod approval because I'm a new member or did I run into a software bug?
