The short version
- Find out what you are dealing withLoad the video or channel in ClearComments and filter to flagged comments. You get counts by signal — spam, scam, insult, criticism, impersonation — instead of a vague sense that it is bad.
- Export the evidenceTake the filtered list away as CSV, with author names, channel IDs and direct links. This is the working list.
- Remove them where removal happensYouTube Studio for hand-picked removals and bulk actions on held comments, or a tool that authenticates as you for large sweeps.
- Close the doorBlock the accounts, add the recurring phrases to your blocked-words list, and consider holding replies from new accounts for review.
First, the honest part
ClearComments cannot delete anything. It reads public comments through the public API and never asks you to sign in, which is exactly why it cannot act on your behalf. Any public tool that claims to delete comments without your login is either mistaken or describing something else.
What it does is the other half of the job: telling you precisely which comments are worth removing, with the evidence attached. Deletion is quick once you know the targets; finding them across thousands of comments is what eats the afternoon.
What YouTube Studio can do
Studio has a comments section with a Held for review tab, and there you can select many at once and remove or report them together. For the spam YouTube already caught, this is the fastest route and it costs nothing.
Its limits are real, though. Published comments have to be dealt with one at a time. There is no search across your whole channel’s comments. And nothing groups the twenty replies left by the same account across fifteen videos, which is exactly the shape a spam campaign takes.
Blocking beats deleting
Two settings under Settings → Community do more than any amount of manual removal:
- Blocked words. Comments containing them are held automatically. Put the recurring phrases from your own export here — the WhatsApp number format, the giveaway wording.
- Hold potentially inappropriate comments for review, and its stricter setting. Blunt, but on a channel under sustained attack it turns a daily job into a weekly one.
Blocking an account stops it commenting again, though it does not remove what it already left.
Tools that do delete
For sweeps too large to do by hand there are open-source tools that authenticate with your own Google account and can delete, report or hold comments in bulk. The best known is YT-Spammer-Purge, a Python tool with a range of filtering modes and a recovery mode for undoing a deletion pass.
It asks more of you than a web page does — Python, and your own Google Cloud credentials — and in exchange it can do the thing no public tool can. It is a reasonable pairing: identify here, act there.
Deal with impersonation separately
The reply wearing your name and photo is not ordinary spam, and it should not wait for the next cleanup. It is aimed at your viewers’ money. Report those through YouTube’s impersonation category, which is a specific reporting reason and carries more weight coming from the channel being copied.
