is it me or is youtube not letting us comment more these days ?

It isn't you. YouTube is not letting us comment as much anymore.

Yes, they’ll remove them too.

These days? They've had ghost bans for the longest time where your comments appear to you but to no one else

Yes, we're not welcome to be heard.
Even when it's open to comments I have been invisible in those comments since 2011. You aren't seen if you are against war three times. I'm somewhat visible to the person I responded to who made a comment, sometimes. The crowd is curated to make war fun for the people who don't care about the ecosystem. And it hides the rest of us.

That’s like Daily Mail, maybe one out of 10 times I’ve wrote a comment they actually post it.

I've noticed that a lot of bloggers on Pinterest turn their comments off.

I've only noticed the comment section acts kind of finicky

Usually its the uploader who turns off comments

It depends on the channel, whether the owner clicked them off, or marked underage content, like a cartoon/learning channel, or a kid reviewing kid's products like toys.
