How to remove spam war banners?

Question

Fight against spam

I'm doing layout and on some projects there was a problem. In connection with the events in the world, some smart people have made it so that everyone who enters a certain site sees a banner about the war, like "We may be fired, but we do not want to be silent." I don’t know who will be fired there, but I don’t need banners covering the entire page ...

Answer 1

https obviously. Insert banners about anything - from war to women's pads, for example, a provider can. Or a host. Or someone else.
PS: Hide the picture under the spoiler, pliz. Already sick of politics.
