Many moons ago at home I knew one of the developers of one of them, the one where some pages you had to pay to access, they were normally about 10p if I remember correctly, he told me they had run over budget and it was getting iffy with those funding it, so they put up a page saying this page is 50p, people thought what could be special for it to cost that much so paid for it to find a picture of a 50p coin…. They ended up in profit lol. Well that’s what he told me.
