To be fair, they don't have any powers. The best they can do is make a ruling but there are no real consequences other than bad PR (unless you are regulated in another sector, like a gambling company for example). Some advertisers require influencers to comply with ad regs in their contracts meaning failure to do so would technically be a breach of contract of contract- which might prevent the brand from working with the influencer again. However, I doubt Ella has entered into an influencer agreement with her own company hehe.
