While I might have assumed you were a blatant spammer in the past, I won't downvote you now I'm more aware of your powers of interaction.
If you think this 'real person' strategy is working for you, I think it would be more convincing if you linked to some content that's not yours (maybe even not youtube). Stuff that you might think others on here would appreciate, or that you personally care about.
But I don't have the rights to anybody else's works and dont have their permissions to post their stuff. I only have the rights to my own work.
You're just advertising your own youtube videos. If you paid some financially challenged person in Bangladesh to do exactly the same thing, surely that would be commerical spam? (Perhaps I'm interacting with the Bangladeshi now, rather than the Persian Canadian...)
Damn, I just noticed you're capable of interaction as a real person, and it's you in these spammy videos!
I have mixed feelings about this.
