Background
The 'voluntary_marmoset_dumbs' package is part of a series of npm packages associated with the tea.xyz token reward campaign.

This results in the continuous republishing of variants that pollute the npm registry, potentially leading to reputation damage for developers and security risks for users who unknowingly install these compromised packages.
