Like there is codereview.see, can we have proofreading questions on this site?
No, at this point in time, proofreading questions are not generally OK here.
One of the "off-topic" reasons on this site is "Proofreading"
Proofreading questions are off-topic unless a specific source of concern in the text is clearly identified. See: Alternative websites for proofreading
Meaning you can't just paste a block of text and ask us to "fix" it for you.
If you have a specific question about your text that you'd like to address, that's different.
I think the reason this could fall under off topic is that it's "primarily opinion based" or "every answer is right".
How to say something correctly is, to some degree, a matter of choice. English is complicated but that doesn't mean there aren't myriad ways to say the same thing.
You could have two or three completely acceptable answers where none of them are actually the same.
I, personally, would have no problem with a question to proofread, as long as the text isn't too lengthy. Others, however, might object under any circumstances. 'Would someone proofread this text example for me?' would be a nonproductive question. 'What would be the correct tense for the verbs in this text?' is a better question because it addresses a specific topic.
