That looks like two posts from one user.
The piefed dev also posts about tankies on MWoG.

So I feel like there's bad faith enough to go around, (like with anything where 'tankie' comes up). The user posting on .ml there was just outright deleted off Piefed by the dev. There's clearly an ongoing thing with those right now.
