Yesterday (September 8), Epic published a lengthy post on the Fortnite site detailing competitive updates for Chapter 2 Season 4. The post covers several topics, including the Hype leaderboard and the Fortnite Champion Series. It also clarifies a lot of things regarding the competitive integrity update the company announced last month.
The “official rules clarification” not only defines what is and is not collusion as well as addressing smurfing and 3rd party software (all things players would expect), it also introduces rules regarding “clout farming”. With the introduction of the new season, Epic will be taking action against players falsely claiming to have been banned. This rule also applies to anyone who claims to be cheating despite not actually doing so.
Aside from just generally being inappropriate behavior, clout farming has the additional impact of forcing Epic to investigate things unnecessarily. So, you can see where they might be annoyed with it.
