Was he fraudulently raising money under the pretense that it was for a charity or some other good cause?
Edit, to clarify: By “good cause” I mean something the suckers . . . er, donors would consider a good cause. But maybe or maybe not what the folks around here, in general, would consider so.
Did he fraudulently sell something, in order to make fun of a company that actually sells something like it? Or to make fun of the sort of people who buy it?
What was he selling, was it a:
Financial product or service
Personal product or service
Home product or service
Business product or service?
How was the trolling part of his crime? did it advertise the thing he was selling? did it develop his persona and celebrity in order to help his sales pitch?
Was what he was selling something that protected people from Igor.?
Was Igor’s convicted of a crime?
Do you actually know Igor’s real name?
Is there a good chance that I know Igor’s real name?
Is it me or does this seem like it could apply to many people like Billy McFarland of the Fyre Festival et alii.
Am I missing a clue that makes the answer very specific even though we don’t know who it is?
Wee that’s frustrating. I vote that to make this LTP more user friendly, we get a clue that at least leads us to think laterally and not guess-and-check.
And usually, in this sort of puzzle, the trick is based on some incorrect assumption the reader would naively make (like in @Buck_Godot 's example, the assumption that they were humans). So good questions will whittle away the space around assumptions, hopefully finding which one is incorrect.
