To hide an Ad you don’t want to see again, click the three dots next to the Ad on your newsfeed, then select ‘Hide Ad’.
Use your ‘Instagram Ad Topic Preferences’ to see fewer Ads based on certain topics.
You can also adjust your device settings to opt out of seeing Ads based on non-Facebook Company Products (e.g. based on other sites and apps that you have visited). This will be in your device’s settings menu. You will still see Ads which Instagram has selected for you, or where you appear on a company’s list directly shared with Instagram with appropriate permissions.
Please note this advice is not comprehensive as social media sites may change their operating policies from time to time. There is also no guarantee that information and settings will be carried over between devices (e.g. shared devices between family members). If you are worried about problem gambling, you may find it appropriate to exclude yourself from gambling directly.
