HERE’S WHAT YOU DO: CHANGING GOOGLE OR YOU TUBE ACCOUNT IS IRRELEVANT. Your IP address has been marked as spam so everything you write from that address will be ghosted. YOU MUST USE ANOTHER IP ADDRESS: use your phone (I also denied Google access to my location when asked, but I don’t know if that’s relevant). Another girl who had the same problem could publish from home, but not from work: IP address change. Google or YouTube account doesn’t matter; I could publish from my phone and be seen when not connected, using my old (which I thought banned) and my new Google account. Only IP is important.CONTENT OF THE GHOSTED COMMENTS IS IRRELEVANT: from the moment you have been ghosted, the process is automatic; everything coming from your IP address will be banned, on every video. So stop excusing yourselves, you have no reason to do so. On the other hand, pay attention to what you wrote just before being ghosted, the last comments you had that were actually published: were they anodyne or could they have annoyed someone who reported you? YouTube doesn’t have moderators, but they do have people watching reports, so if someone reported you and the guy from YouTube could not officially ban you, as your comment did not meet criteria (was not violent, etc,) but nevertheless didn’t like it, it is probable that he marked you as spam. Replies are more likely to lead to ghosting than new entries, as they would be statistically more confrontational for obvious reasons and therefore more likely to derange. A spam filter wouldn’t concentrate on replies, as must spams are not replies, but new entries.
Another explanation would be that you have been marked as spam by somebody capable of hacking the YouTube spam filter. Same solution here.
Hope this is helpful.
