Macri, who was Mayor of Buenos Aires for 8 years until his narrow election to the Presidency last November, was well known for his authoritarian (sometimes illegal) brand of gutter politics - including the use of hundreds of paid internet trolls.
These mostly worked out of a Brown Shirt-esque "Special Projects Unit" led by Paula Uhalde. Millions more in vaguely-worded city contracts have gone to media hacks such as Fernando Niembro and Luis Majul, the latter becoming especially notorious for his "anonymous source" hit pieces alleging corruption on the part of Macri's left-wing predecessor (again, while himself collecting millions in taxpayer pesos to do so).
They mostly plague Argentine news site comment boards, although recently they've been showing up on English language sites as well. Right-wing outfits from several other Latin American countries have done likewise (including, quite possibly, here on DU).
We know Paul Singer (the Cayman Islands vulture fundie who's demanding $3 billion on old defaulted bonds he purchased for $48 million) bankrolled some of this - mainly through a "non-profit" run by the Michelle Bachmann of Argentina, Congresswoman Laura Alonso.
As it happens Alonso was then named head of the Federal Anticorruption Office by Macri, and is now on full damage control mode over her boss' Panama Papers revelations (the very thing that she's entrusted to prevent and prosecute). Not that it did him any good. Her bumbling rationalization probably did as much political harm as the Panama Papers themselves.
At any rate, thank you for sharing that very intriguing anecdote, Zach. Their unhinged, childish reaction to your wife only shows them up for what they are.
Qué será.
