There have been plenty of moments before that that should have got them cancelled. The rape joke, for instance. It lost Anna her 'job' as a columnist for the Asda magazine, but not much else happened.
The live chat also comes to mind. He promised to call viewers, resulting in lots of underaged girls posting their phone numbers in the chat. He then picked one to come on video with him, telling her to make sure she 'looked nice'. And where was all this? Oh, and adult website, resulting in lots of those girls being harrassed by disgusting blokes.
I am still surprised no stories came out after his cycling meet-up with his 'fans', which turned out to be only girls if I remember correctly. He had it set up with a guide that would take them through the area, and oopsss, he got lost with just a small group of them.... I guess he had them all sign an NDA, or else I am sure we would have heard more.
How Gleam did not dump their arses any sooner, I have no idea. They seemed a liability from the very start.
