pkgcheck supports skipping ebuilds results via special annotation. This is useful in cases where you are aware of false positive in pkgcheck check, and fixing pkgcheck is hard or impossible.
The annotation must appear in the ebuild before any non-comment non-empty line (most of the times it would be just before the EAPI declaration line and after the copyright lines). Empty lines between the copyright and the annotation are allowed.
You can't skip error level results. Skipping warning level results requires QA team member approval (should include name and RFC 3339 data). info and style level can be skipped without approval. Do consider to just ignore them instead of skipping.
An example of skipping a info and warning level results:
