> if you are scrolling on mobile, they've changed the behaviour on iOS so that if you touch the ad at all, it considers it a click and opens it,

They did it for Android, too. Just the other day, I tried to view replies for an ad, and thought I'd accidentally clicked the ad multiple times before realizing that the replies indicator and even the timestamp (which is the normal "just go to the tweet" valve) were behaving the same as an ad click.

Edit: Re-reading your comment, not sure if that was exactly what you meant, or if you just meant that it'll e.g. open the ad if you try to scroll on it.
