Why is this the sub not pro Bolsonaro?

One thing that really baffles me is that, unlike Argentine subreddits, Brazilian subreddits have not been taken over by pro-Bolsonaro trolls and his genuine supporters. There are several reasons why this has happened in Argentina: Milei's supporters are overwhelmingly young males, who are the most online constituency; the government allocates resources to fund trolls and fake supporters; and Milei remains somewhat popular among the electorate as a whole.

My understanding is that Bolsonaro still maintains support from his core constituency. So why isn’t he more popular on the subreddits?
