Sorry, what's a "Q symbol"? That post is a picture of five people showing "thumbs up". And again, Trump doesn't get to pick that ID. It's generated internal to Twitter, the "message" you're imputing here isn't coming from Trump, it's coming from TWITTER.

Edit: also, you're making a classic numeric error here. The likelihood of that particular "message" (DOITQ) in isolation isn't the number you're interested in, because other than the letter "Q" it doesn't contain any actual information to verify. You'd be here saying exactly the same thing if it read "DoItQ", "GoQ", "QAnon", "IluvQ", etc...

There are literally MILLIONS of trivially constructable 1-5 character strings that might be interpreted as a "message" to someone that wants to see a message. And needless to say Trump has tweeted many thousands of such "messages".
