Spamming links on YouTube dangerous?

I want to promote my articles in the comment section of niche related videos. If I post my link too often YouTube will potentially ghost my comments, but does it also effect my rankings in a negative way? How to prevent any possible risks?

Thank you very much for helping me

It won't impact your rankings as long as the video is in the same niche. You have to post a lot (like hundreds or thousands a day) on irrelevant videos to impact your rankings. As for ghosting your comments try commenting on other people's comments
