I'm using Chrome browser on Android.
Normal website behaviour is for ads to only detect a click if you tap and let go, not if you swipe.
Since the update, ads on MN detect a click even if you swipe (that is, press and drag, not tap and let go), intending to scroll the page. I understand ad clicks might be your favourite thing, but I'm sick of being hauled off to another website every time I swipe to scroll the page and my thumb happens to have landed on an ad.
Can't see anything else on the front page of Site Stuff about this — is it on the snagging list, at least?
