I lived and worked in that area for many years. I have walked through Whitechapel day and night. Yes, there are a lot of Muslims in the area due to the nearby mosque. The only violence or trouble I ever experienced in the area was with other white people. Whitechapel is a busy part of central London, if you're going to choose a part of London to claim that there is a no go zone, at least try somewhere that isn't on the tourist track, like Poplar (although that isn't a no go zone either, but it's at least a little more plausible).

"Auditing" videos are antagonists causing trouble and videoing it, often either deceptively editing or outright fabricating interactions. People, of course, have strong views, regardless of race or religion, and antagonising them is going to bring out the most extreme of those views. Going to an area with many muslims and trying to antagonise muslims does not make a no-go zone. You can go to whitechapel any time day or night and the only risk is a pissed up local, which, ironically, won't be a Muslim because they don't drink. Alcohol is the main cause of danger in London.
