I'm not sure about what the guidelines say, but I personally consider that it's fine to make exceptions for regular users from time to time when it is needed. Your account has almost 8 years, so I think this is fine. (This is not an official opinion, I'm just someone that read the newest page too much.)

But the submission has 4 (dead) comments by accounts created just now, probably just to comment here. And the comments are very short onliners. It is fine if someone creates a new account to provide more details and information, but it's not fine if the comments are not sustancial.

(For example if one of the regular users my ask for more details or info, it if fine that the doctor or some familiar with more knowledge may create an account to answer. But the answer must have more details, let's say three paragraphs.)

(It's not fine if a new account ask for more info and then a new account answer it. It looks like a fake Q&A.)
