What to do about hijacks?

Fourthed, or whatever we’re up to. “Should” comments seem to be the source of many hijacks in news threads.

I tighter rein on FQ would be nice, too. Nobody cares what your mom did in nineteen fifty whatever. That thread is 80% pointless clutter by posters who just cannot resist the urge to treat FQ like an IMHO poll. It took 11 hours for a mod to show up and ask if the hijackers should be rewarded for their efforts, then the next day for another to finally ask that it stay on topic.
