Isn’t that awfully aggressive?
Not sure how D5 is used here. Seems to have different meanings. see the Lexicon here: http://www.freerepublic.com/~swordmaker/index
“Q” used D5 in drop 1332 in May 2018
then
“Q” defined D5 in drop #2494 as December 5(2018)
“Q” then used D5 afterwards (Drop 3365) and I have no idea what it means.
