I can’t tell you what it said, it was edited on the old software which didn’t track edits.
The post isn’t actually blank, it contains the text “[removed]”, but interestingly that string shows up as blank, possibly because it’s a BBCode tag. It doesn’t even show up in a code block (thus the weird formatting above).
I assume you changed your mind and removed the post and left a placeholder. If it had been a mod it probably would have been deleted completely.
Sorry I can’t be more helpful.
EDIT: Could be the quoted text here, posted about 2 hours later:
