Well, this might be the small-time YouTuber speaking inside me, but I do feel empathy for you. It's pretty tough, putting effort into your videos just for them to barely get any traction. Then, when you try to advertise your channel, you get hit with backlash and/or silence. It really does hurt like hell.
I see that you've set up an account, and have even taken the time to add things like your favorite genres and anime on your profile. You're clearly putting some effort in, but please know that Anime Forums really doesn't like it when it gets spammed. You can find the rules here. I didn't really understand a lot until I had spent more time here, but I've come to realize that there's a tightly-knit community here. It's a bad look when you disregard that community for your own gain.
Since you've spent a while on your channel, (I looked around on YouTube, and found a channel that I think is yours) I'm assuming that you're going to keep trekking on this journey. I've been on and off with my content, but I'm here for the long haul, too. If the both of us keep uploading and getting better, I'm sure we'll be noticed one day. As for Anime Forums, the people here are very friendly and welcoming, so I'm sure they'd forgive you if you show an effort to seem like you're willing to become a part of the community. I'm a newer member myself, you know.
This was kind of rambly. Sorry about that. Maybe the empathy I have for someone who's struggling in the same way I have makes me want to encourage others, so that they don't feel as lonely as I did. I don't know.
Good luck, buddy.
