YouTube Traffic Strategy

I am trying to manually spam YouTube live chat section, but I am not getting any clicks to my link whatsoever.
I use bitly as a link tracker and I don't explicitly type the URL in the chat, instead, I type it as bit(.)ly/my-link or bit(Dot)ly/my-link

Can someone tell me what's wrong?

Also, does anyone know a good strategy to spam YouTube (besides live chat) in order to get instant traffic

Try advertising in different forums like Reddit for example, spamming won't help you that much. Good luck
