@ItsCrisDiaz It happened to me recently, and kind of shocked me.
In my home banking web page.
A warning that told me that terms and conditions of my account have changed, and I needed to review them.
In a modal dialog.
As a picture.
With "Campaign" as the sole alt text.

What really shocked me is that we've been working with them for years... (We're a small fry asking the other providers, but still... That is actually illegal in Europe.)
