Oh dear
I suppose if I don't look up I won't be spammed by aerial adverts.
When I'm World Emperor I will ban all adverts except in Retail and Trade directories. We have the Internet and Google / Amazon / eBay / Alibaba etc are already enough to find any product you want.
Random unsolicited adverts are so exploitive and Victorian. Ban Door to Door sales, spam email, mail fliers too.
Some manufacturers / retailers would save up to 15% .
