1. In the left sidebar click on History tab ("Иcтopия" on my screenshot). If you don't see it, click on the three horizontal lines located to the left of the Jewtube logo and the sidebar will open.
2. In the "History" section click on the "Comments" ("Кoммeнтapии" on my screnshot) tab to be able to see all your anti-semitic comments. From there, you can delete them all so that your kike boss doesn't find out that you're a nazi supremacist.
Be careful goy!
