I asked for votes for a video submission contest I put up on my second channel. On my main channel I asked my audience for help by just voting on the contest website. I got lot's of nice comments and support but also 13 unsubscribes, but whatever.
Youtube tip: Don't ask your audience to help you. Granted I received way more genuine support from my fans and for that I am humbled and so thankful. But others don't give two shits and want no part in another person possibly winning an online contest. I deleted the video asking for help on my main channel (I was going to anyway) but fun story the video got 15 likes and zero dislikes and lot's of nice supportive comments. Yay me!
