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.
Not that I'm an expert, but I'm pretty sure you misunderstand the situation.
Whether it's youtube or a news article, if you copy the entire content and host it somewhere else I think you'd need their permission to do so.
Just posting a link to other people's content on youtube or their website is advertising for them. They pay people/bots to do that. If you like the content - sharing a link to their content on their preferred host is doing them a favor. (Of course if everyone on Phuks hates the links you post, you won't necessarily be doing us a favor, so a little give-and-take is good.)
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.
