What control do authors have on comments?
None. Authors can’t moderate comments on their own (or anyone else’s) articles. If an author wants a particular comment removed, they need to make a complaint via the report link (as above) and it will be assessed by the moderation team in due course and dealt with accordingly. The moderators work closely with editorial staff to determine and maintain an appropriate, context-specific community environment, informed and supported by the sitewide community standards.
