Wow, great example, and great example of what these fakers do when called out. Summary:

The maintainer, instead of listening to the security researcher and accepting feedback about his development process, instead:

1. Denied the problem

2. Censored discussion of the problem

3. Banned the people calling out the problem

...and then when the security issues were posted more publicly and got traction...

4. Made the subreddit private

5. Wiped and deleted his account

6. Wiped and deleted the GitHub repo

7. Took the project's web site off the web

Absolutely wild and unhinged behavior.
