Does the text sound native?

Pretty much, it does. Better than the late night spam we get on a2k.

nope


the last sentence in particular is a red flag to the blurb being a translation

It's a mess.

I don't have time to make all the necessary corrections right now.

Joe(I'll be back)Nation

Thank you.
The thread closed.

But, does being a mess disqualify native speakers?

Thread closed?

You'll shut out Joe Nation to come back and help you?

He wasn't insulting you, per se, but saying there is a lot wrong and he would be back to attend to it. That is what mess means. Things to be fixed.

Set has helped you many times but you are done with him.

What a prince.

Please, make no misunderstanding.

Joe has been kind and cool, and of course still is. I said "closing", which never means he's done anything improperly. English is a great language that deserves lifelong effort. I meant "Move along" just because I am not much interested in the passage in the first post here.

Set is cool as well. But it is he who is done with me, and the reverse is not true. For example, he said "it is false" when I spoke about King's English. Because in his mind's eye, only Queen's English is authentic and authoritative. As I argued with wiki-based evidence that Queen's English is often paralleled with King's, he showed contempt on my point (he particularly emphasized that he "not showed with anger on my view". And I replied "I know my English is flawed and fallible; you've got the opportunity to show your contempt. It's fine; let me see when you will stop." What more can I do to ease the situation? He's that old dog who as usual refuses to budge.

I take "thread closed" to mean you've gotten all the answer you needed. Nothing more.

Ditto..

Ok, folks, sorry, I misunderstood Oristar.
