Facebook does not intentionally give out fake likes on ads. However, it's possible that some of the likes on your Facebook ads may come from fake or inactive accounts.

Click Farms: Some unscrupulous businesses use click farms to artificially inflate likes, followers, and engagement on social media accounts. These fake accounts are often created in developing countries and are used to like, share, and comment on posts in exchange for payment.

Bot Accounts: There are also automated bot accounts that are programmed to like and engage with posts on social media. These bots can create fake likes and engagement on Facebook ads, making it appear as though the ad is more popular than it actually is.

Inactive Accounts: Some users may create Facebook accounts and then abandon them, leaving them inactive. These inactive accounts may still be counted as likes on Facebook ads, even though they are not active users.

It's important to note that Facebook takes fake likes and engagement seriously and has measures in place to detect and remove them. However, it's possible that some fake likes may still slip through the cracks.

To ensure that your Facebook ads are reaching real and engaged users, it's important to focus on targeting the right audience, creating high-quality ad content, and using Facebook's ad targeting and optimization tools to reach users who are more likely to be interested in your product or service.
