This is the "serve shot clock" discussion.
You can control this with what you already have at your disposal, namely the Ignore and Report functionalities.
What I think people are after here is punitive action against people for constantly bringing up the doping thing out of context with the discussion which again is handled by either the Report or Ignore capabilities of this forum.
I personally think random drags are Ok. It's what gives this forum flavor. Just like when people used to bring up Shino randomly (of which I have receipts on hand...), so long as it doesn't get into long drawn out WADA-bylaws quoting debates that derail the thread, I think people will live.
People should just Shade Responsibly and use the methods at your disposal to make your own forum experience pleasant instead of having the mods litigate our entire lives. That's how we lost "Bye Bitch" gifs and I'm still raw about that.
