Posting scripts and third party tools like these on the site is not allowed for a few reasons, the main one being they often contain malicious software, such as keyloggers, etc.
While your intention may come from a genuine place, and the software you link may be fine to run, the bottom line is all such tools are prohibited to be shared on the site. The
few outliers to this rule are added in stickies.
Hypothetically, you could push out a version tomorrow that contains malicious content. Not saying you would, but that's an outcome we have to keep in mind. At the end of the day, our users' safety is paramount, and that's really the bottom line.
As for the suspension, like you mentioned yourself, you didn't wait to hear back from the site staff you contacted and went ahead and posted the content in question, before you received the go-ahead. Next time, wait for that reply.
See rule #12 & #13.
