Paid Fans
It says a lot about the 2022 World Cup that Qatari organizers agreed to pay fans to hype up the tournament. They instructed different groups to promote the event online and provide positive messages about the tournament. Furthermore, they also wanted them to downvote and report negative commentary about it.

The world’s media discovered what was going on and came out strongly against it. In the end, Qatar said that it wasn’t happening and canceled payments to the supporter groups. Some fans claimed that the government approached them but they refused because they didn’t want to sell their souls (via The Guardian).
