Rule ID	`adblock/element-hiding`
Category	Adblock Detection
Scope	Site-wide
Severity	warning
Weight	3/10

Solution

Elements matching adblock filter rules may be hidden for users with adblockers. This can affect ad revenue or hide legitimate content if element names/classes match ad patterns. Consider renaming CSS classes that unintentionally match ad-blocking patterns (like .ad-*, .banner, .sponsor).
