That's how it has always been for all places. Admins have the power to erase anything that goes against Reddit's ToS. Depicting spez under the guillotine is against their ToS, but writing "fuck spez" isn't, which is why one gets deleted and the other remains.
It makes sense IMO. It's just like admins having the power to erase swastikas, homophobic or transphobic content, blatant product advertisements and so on. Nothing wrong with it, IMO.
Him recruiting the News Coo does sound a lot like Luffy. Though obviously the "mutiny" comment is more this new Live Action Luffy, who also looks to be very funny IMO.
