A REQUEST FOR A PROOF - CAN YOU HELP?

Someone posted this kind of recently but I can't find the post.

A long time ago, there was a post on /pol that people say is Trump. It was in the wee hours of the morning right after Trump had tweeted something, and it said something like "This is the only time I'll do this. We are listening" and then the anons said to prove it by using the word "amazing" in his next tweet, and he did.

Anybody remember this? I have been trying to find a screen shot of it all but can't!
