Is there a new Moderator in charge of this section
Yes, "
frodocooper" is the latest addition (
Welcome frodocooper as new moderator to mining).
has the section just been tightening up what post are allowed there?
AFAIK, the rules are the same (
BITCOIN MINING INTRO & RULES OF THIS SUBFORUM - READ BEFORE POSTING). Not sure what was added on "Dec,13,2017" (date of the last edit) to that thread but from the looks of it, moderators are simply doing their job (I've noticed a lot of cleaning up, after the addition of "frodocooper").
