The question that I've deleted after I edited it and downvoted was
math.stackexchange.com/questions/4430576/… (now it is in MathOverflow) As I've flagged in many ocassions I got many downvotes (from a weird user), I'm flagging (I was including legal threats in my dozen of flags) this violence against my person and the ownship of Mathematics Stack Exchange. Be serious and read my flags @XanderHenderson
