Unexpected help...

A small story about "How someone can help when you don't expect it".

I am single, not native English (I am from Ukraine) who trying to run the SaaS tool.
And I testing how to communicate with the different audiences on different resources/sites.
At the same time, I don't want to post a "fake" post just for testing so I asked to help I really need it. It's a grammar/native check for one page (description about one feature).
I was waiting for some comments about some grammar problems but didn't get any comments.
— Okay, no problem, moving forward...
But later /u/etiloxi sent me PM with link to PDF with ALL fixes.

It was unexpected and so the impression me! So I used all devices even when it was variants list (so now on the page I have one place when you can see one phrase and can reload the page for seeing new one).

Did anyone have similar unexpected help from strangers?
