Я вашу претензию понимаю, но я не в полности согласен.
I think that BappaBa should have a .sig with the following: "If you are learning Russian at the beginning to intermediate level, please ignore everything I say. Advanced learners of Russian, pay attention!"
People who have studied Russian for several years can learn a lot of useful information from BappaBa about colloquial and slang Russian, but beginners shouldn't take his advice because they'll get confused.
