MTStars has a limited control over the Ads being shown to it's visitors by Google AdSense.
Google shows Ads via contextual advertising (based on the webpage content) and behavioral targeting (based on visitor's recent Google searches/browsing history etc.)
However, you can always define your Ad preferences for Google Ads here:
https://www.google.com/settings/ads/plugin
On a broader level (apart from MTStars), you can set your behavioral targeting preferences for web surfing here:
