It pops up all the time, it’s a waste of time and I’m sure it has been used countless of times to discard some piece of information. It doesn’t add up anything productive to the comments, people who comment don’t even say anything they actually think they just “did you know that MBFC says this so it has to be truth?” I could go on but I think you get the idea.
Should have a standardised response to MBFC getting posted, like the one Davel posted.
I don’t think a bot is worth for that, no one will read it anyway, just delete the comments.
