We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Feature: forbid `credits()` builtin function
We should add `credits()` as a forbidden function:

```
» python -c 'credits()'
    Thanks to CWI, CNRI, BeOpen.com, Zope Corporation and a cast of thousands
    for supporting Python development.  See www.python.org for more information.

```

We need to add it here: https://github.com/wemake-services/wemake-python-styleguide/blob/3cedeb3c13ab6b16980a39edf657ab93d4c1f19e/wemake_python_styleguide/constants.py#L36-L38
