I was on the Daily Mail site (bad site for tracking) today already reading for a while, when I got a full screen pop up that looked legit asking if I was a robot. I just quickly deleted the site and checked online to find that it is a major scam right now. Several are reporting it from different sites. Just beware.
If it happens when trying to log in to a site, it is less likely to be a scam, for more secure sites, or when making purchases, but I'm not very trusting after my event and have never had this happen with the Q. Maybe we should ask the Social Team.
