I don't know where your rep was before but 63 rep is not dead. He didn't touch your earnings.
It is a flag, it is uncomfortable, I've received them as well. It doesn't actually cause physical pain nor does it equate to violence.
immutability is built into the blockchain earning isn't. I am not defending this, but I am having trouble following the extreme language.
He flagged you, he didn't knife you in the alley.
"didnt knife you in the alley" hahahaha
What happens there is that reps above 60 (or is it 62) do not get reduced by down-votes, but her complain as i understand it; is that when she posts she gets down-voted by several accounts, in this case, the interface still dims the posts because of the amount and stake of the down-votes, not because of her rep.
