Youtube labelling for life!

In Youtube's wisdom using their algorithms to analyse and influence its users to watch what they deem the user wants or should watch, they are getting it all wrong. I watched one video about a prison in South Africa, and now no matter what I search for every second result is about prisons. The same happens with whatever I watch. My suggestion is every time you watch something on Youtube, use a cleaning program to clear your Youtube history or you will be labelled for life! And the CIA loves that.
