YouTube's spam policy does not ban robots and bless humans. It bans a pattern: repetitive, irrelevant, or promotional comments, posted at volume, across videos the poster did not watch. A human pasting AI drafts across fifty unrelated videos fits that pattern just as well as a bot does.
The clearest official example is the comment that exists only to redirect viewers: "check out my channel" posted across hundreds of videos. The words are human, the intent is promotion, and the pattern is what gets actioned. One thoughtful comment on a video you watched is the opposite shape.
What happens to a comment that trips the filter is quieter than most creators expect. Comments held for review sit in YouTube Studio for at most 60 days. Comments the system hides outright never reach Studio at all, and the commenter is not notified. Posted does not mean visible.
That is why "draft only, human posts" is necessary but not sufficient. Having a person press publish does not rescue a comment that is generic, off-topic, or promotional, and it does not rescue a campaign built on volume across unrelated niches.
Safe practice has a boring shape, which is the point: watch the video, comment on one specific thing in it, say something only a watcher could say, ask one genuine question, leave your channel out of it, and keep the frequency human. Then use a quality check on the draft before you post.
That is what tarelivo's free tools are built around. The generator drafts ideas, the score checker grades them against the spam signals above, and nothing posts automatically from the free tools. The workspace adds monitoring and scheduling, but the rule stays the same: specific, relevant, reviewed, and human-paced.
