[Meta] Posts being deleted by mods for "cannibalposting"?

2 recent posts I made were deleted with the reason "please refrain from cannibalposting" (link to the modlog). I don't get how this is a rule violation and I don't remember r/196 ever removing posts like that.

In general I thought the concensus has always been that 196 is only moderated to remove bigotry and the like, I fail to see how this would be in spirit of the subreddit :/ (unless I'm missing something)
