They seem to be getting in everywhere these days. I was reading a local newspaper site*** on my phone the other day and accidentally clicked on an ad rather than scrolling the page up. Next thing an age verification box popped up over some blurred images which definitely didn't look like Yorkshire townscapes!!
***Or should I have said '
Advertising site which had some local news on it'? The ad-to-content ratio is getting ridiculous on many sites now!
