Some apps offer an upgrade option where you can pay a few quid and get rid of adverts.
I wonder if this might be doable on the kitz site. Basically, you go to the kitz shop and effectively buy a cookie, which sets a no adverts css option.
I can imagine this might be a nightmare to implement, better things to do, platform doesn't make it easy at all, and a hundred other things.
Some of the recent flashing ads at the top have been making my eyes hurt, hence the reason behind this thought experiment.
