3 days is a very short ban. So until this is cleared up, you probably have it back.
In your history, I couldn't find anything to go on. Maybe the posts were made a long time ago.
While I agree that 3 days is short, my main is part of a signature campaign so this would not look good if the CM notices my inactivity during the duration.
I don't recall spamming reflinks back then either, but if there's evidence I did so a long time ago, I'll take responsibility. All I hope is that the responsible individual would actually come forward so I know it's justified.
Because if the same thing happens again, something's not right.
Or maybe it was via PN? PN-REF-Spam is also forbidden!
What's PN-REF? Never heard of that before.
