Yes it's possible, but is it allow? I have an account that gets 2-3 new subscribers on autopilot, search engine results for a popular topic, 100+ subscribers, and made a sale on Clickbank just by posting a URL in my profile....all while doing nothing. Does youtube allow that?
I'm sure account trading is allowed. You see all these big named youtubers getting rare names such as "Fred" and "Damien".
