I found someone added a webapp I made to their site in an iframe.

The 'dark' box at the bottom of the screenshot is my webapp.

I don't really mind them iframing it. I hate adverts but I don't mind that much that they have adverts on their site.

I am very annoyed however that they have a huge overlay appearing on top telling people to turn off their ad-blocker. Also they use alert() to tell people to share their site on social media!

Being told to turn off my ad-block and having to close alert popup boxes are two of my most hated things.

So now I made a little update to my site so their visitors will see a nice little song playing.
