Accounts are banned for an action, but why?

Hi there,

I used to post a repo in GitHub where I use GitHub action to publish the NPM package. This action fetches icons from Figma and processes them, then publishes them as an NPM package. Some users contact me recently because their accounts were banned while they are using this workflow. I read the service terms but don’t understand which one is triggered. Actually, this repo was inspired by an action GitHub is using.

This is my workflow:

Please tell me the specific reason. Thanks.
