I was checking out the actions/checkout repository, which is something most GitHub actions are bound to use, and navigated to the issues:
https://github.com/actions/checkout/issues
On the first page alone I found cryptocurrency scams, zero-effort issues, and outright spam, from days to months old. It is an official GitHub repository for one of their most popular actions in a major feature, with hundreds of watchers and thousands of forks and stars. Yet it looks abandoned.
