CALL OUT people when you see them undermine and defame FF's success by passing off conspiracy theories as truth for the sole purpose of bringing them hate. They will tell you "tHiS iS nOt SaBoTaGe", but technically spreading conspiracy theories, causing psychological harm to employees (the members) and spreading negative publicity about the business (their company) would be considered sabotage. With them spreading hate and doing a smear campaign, they are damaging their reputation and image, and they are also telling people in their fandoms to do the same.
People are allowed to theorize or speculate, but not present their ideas as fact when nothing is verifiable, except their deep seated jealously of others getting success. A lot of these people are Big company success stans, who if they were following kpop during BTS nugu years would treat them just the same.
