Even if he did admit to being a troll he could have made it up wind people up even more. Not saying that its' right thing to do. Either way I don't let myself get wind up. He seems to have a good knowledge of club's history and players so he doesn't appear to me at least to be a troll. What's this obession that foreigner can't be a real fan? What does it matter that someone can't attend a Spurs game got to do with being a fan or not. Depending where they live it may not even be feasible financially/time wise. They may still buy merchandises or simply following the club would be enough in my view.
The object of a troll is to wind people up, if he admitted to trolling to wind people up, then that would also be trolling.
He posts deliberately to provoke. He was more interested in deliberately pissing off Spurs fans than he was supporting the team.
Not sure how you can think he isn’t a troll. All the signs are there.
