Quite right.

• Someone posted that a vegan diet is ok for cats
• Someone else posted that no the fuck it isn't
• !vegan mod removed the previous post
• Admin (presumably Rooki) restored the deleted comment and deleted comments that a vegan diet is ok for cats
• Mod flipped the polarity of the reversals back again, and banned Rooki
• Rooki unbanned themselves, flipped the polarity back again (so now it's only the anti-vegan-cat comments)

So I was wrong, I think. The !vegan mods did delete some of the debunking first, but it wasn't from Rooki. I think.

Also, it's still going on; the mods are as of a few hours ago still undeleting vegan-cat advocacy comments and banning people who disagree with them.
