A banner is shown in the middle of the page. I'm not 100% sure it's an ad. However, it looks like one.

Could you please check if this is considered an ad and if so, please block it?

I would suggest that the image is self promotion given the network's attendance at the event; it appears to be a real and relevant link on the page.
