Whoa dudes!
First, people can't be expected to be allowed to call themselves engineers and have everyone accept that. If that was allowed you would be referencing "Engineering Disasters XXXXXXXXXXX" where the number would equal the number of hamburgers sold at McDs.
Second, the spiral galaxy position you point to should be second guessed by the fact it is signed by "TacoMan". It references another article quoted here..."A barred spiral galaxy is a spiral galaxy with a band of bright stars emerging from the center and running across the middle of the galaxy. Spiral arms appear to emerge from the ends of the "bar" in these galaxies, whereas they appear to emerge directly from the core in ordinary spiral galaxies." Note in the first sentence that a "barred galaxy" is a "spiral galaxy". Kinda shoots holes in the reference doesn't it?
As to the remaining question, what responsibility will any individual bear when he tells a team to connect a power connector to a PWM output? The answer is none. His self imposed title will not prevent the damage or replace the defective unit or help advance the understanding of electrical fundamentals. Although there is no insurance that a working engineer will give the correct response, the odds are weighted in his favor of being correct. Even I am not infallible and will make mistakes from time to time but I will tell you when I don't know or can't remember. That is a call to another engineer to step in and accurately answer the question. Luckily, there are an abundance of individuals who post here who can be trusted for their answers. The signature tells a great deal, I sign as an engineer/mentor, born in 1951, and rookie in 1996. You can derive a lot of pertinent data from those three statements. Contrasted with engineer, born in BLANK, rookie 2005.
Now guys, I hope you don't think I am beating up on you, I am passionate about this particular issue because I have seen damage done by those who call themselves engineers who are not. I want everyone who asks a question to get an accurate answer the first time, and will know that forevermore, they can ask a question and believe in the answer.
