Fitness vlogger and entrepreneur Mo Bicep, stage name of Mohamed Lemhadi, has bought at least 98,000 fake followers and 27,000 fake likes.
Because he is thereby misleading his real followers, the regulator Authority for Consumers & Markets (ACM) has intervened.
"The use of fake likes and fake followers can paint a more positive image of the company and its products than what it is in reality," ACM writes.
"This misleads consumers and that is prohibited."
Lemhadi trades in sports supplements through his company Bicep Papa, which he promotes on social media.
It is the first time that ACM has imposed a sanction for deception through fake followers and likes.
The fake followers were bought for, among others, Lemhadi's personal Instagram account @mobicepp.
Thousands of followers were also purchased for the @mobicep_motivation and @mbnutrition_ accounts.
The regulator is threatening with a penalty.
If Bicep Papa buys fake followers and likes again, the company has to pay an amount of up to 100,000 euros.
Also, all previously purchased fake followers and likes should be removed from Instagram.
An ACM spokesperson said that Bicep Papa has until the end of January to show that the fake accounts and likes have been removed.
NU.nl has tried to reach Lemhadi through Bicep Papa, but at the time of publication no response was received.
