Over the last couple of days, I've started seeing bursts of large numbers (i.e. 10-15) of older questions being flagged for closure. Is this a change of policy being implemented or is some individual decided to go off farming the content on their own?
My general feel from the way I'm seeing these review requests coming in is that it's an individual and I see nothing on meta indicating a policy change, so for old ones I've been flagging as "leave open" because I don't see any purpose to a qusetion that was asked and answered in 2012 or before suddenly needing to be purged, but I thought I'd mention it in case I've missed some policy change -- or to warn out that someone seems to be doing this to the content...
