@Holo I made this minor edit merely in order to bump this meta question. Instead of making malicious guess about others' thoughts, why not gathering enough evidence first to judge others?
@XanderHenderson Maybe using bold face is entirely polite? I don't know where comes this "entirely" thing.
@user302797 You were not pingable, hence there was no way to know your motivation nor to ask you about it. That being said, I don't see anyone "judging" you; just speculating about your motivations.
@user302797 I don't follow what you are saying here. Are you objecting to the fact that I emphasized the fact that one of the three changes you made was actually incorrect?
@user302797 Bold face is for emphasis. amWhy objected to the fact that the edit was trivial; I objected to the fact that it was not only trivial, but incorrect (you capitalized the first letter of a word following a colon; this was a grammatically incorrect edit).
The only other edits you made were to remove contractions, which are a matter of style, and were entirely appropriate in the original version of the question.
As to @Holo's comment, he was suggesting that it is rude to bump old questions via trivial edits. As stated above by @MikeMiller, edits are for improving questions, not bumping them.
How can I be sure I'm looking at a sockpuppet?
You can't ever be 100% sure. What you think is a sockpuppet could in fact be my good friend Nog Shine, who loves everything I write, copies my writing style, and uses my computer to vote and post stuff when I step away for coffee.
But in practice, ...
It is certainly possible that this particular user tried genuinely but Problem Statement I want answer XX. I tried - <Multiply some stuff> = YY seems to have pretty much become a standard template to post such things.
@user334732 No. It is not a sentence following a colon; a colon does not end a sentence. It is part of the previous sentence, and should not be capitalized.
@AlexanderGruber. I am anxious to see the next step with this question. I don't want to be a bother or rush you or anything like that but I hope you'll ping me if/when you decide to do something with it.
