I'd never seen banners until a few years ago at the international in Sydney, there was a massive Japanese delegation who spend the days in 35C heat in their many layers of kimono the poor dears. One lunch session they were scheduled to sit in the sunniest spot of the stadium and a few were sent to hospital with heat stroke.
Anyway back to the banners... there was a lot of that kind of thing being paraded around after the close of the sunday session. Much weeping and handing out of contacts. It touched me a little, but only until my family started arguing.
Why would they be concerned about the link being posted on internet sites? Doesn't that just improve their google rating?
