First time I saw that used as "Quoted For Truth" I didn' know of it and got pissed as I was under the impression it ment "Quit Fucking Talking" as that is the only use I'd seen for that acronym previously.
I always thought it meant "Quoted for Truth" so I've been attaching that to the end of quotes I agreed or thought was humorous. I think I may have guessed at the meaning at some point. The bad part is if I had this all wrong, I may have pissed off some people I meant to complement. For the record (why do people spell it ftw unless it meant something else), I have also seen "quoted for truth" spelled out on several occasions.
I'm glad you brought this up as I will make sure to spell it out from now on so people don't interpret he wrong meaning...

Question: What Is 'QFT'?
While participating in an online discussion forum about immigration laws, you see this strange expression "QFT". People post phrases like "QFT...well said" and "QFT +1".Answer: This peculiar QFT acronym expression stands for "Quoted For Truth".
It has two particular meanings when used in a discussion forum or a heated discussion on a Facebook page or other debate topic.
1) QFT is an expression of agreement and support, where the user stands behind you and one of your statements. This commonly occurs in controversial topics where opinions are very heated, and people will choose sides in an argument.
If someone "quotes you for truth", they are paying you a compliment and siding with you in the discussion.
(User 1) @Pdawg above: QFT +1! Vaccines are indeed proven to be effective. Any of you who argue against vaccines don't understand science!
(Shelby) QFT: Trump is a mysoginist, and the audio recording link above proves it.
2) QFT can also be used to preserve an original forum post, so that the original author cannot edit after the fact. A user who copy-pastes the original forum content will sometimes put the letters "QFT" at the top of the copy-paste. It is a type of forensic stamp used to point out someone's flawed argument in a debate. This is common in serious conversation forums where the users engage in heated discussions on controversial topics, and they are very experienced at making online arguments. The QFT stamp snapshots the original argument into a new post so that the original author can no longer change their original text.
The original author is prevented from denying what they originally wrote because the QFT public copy can refute any denial.
From urban dictionary:
1. Quoted for Truth
Has the same usage as Quoted for Emphasis (QFE)
2. Quit Fucking Talking
Sometimes casues confusion as it has the same abbreviation as something that means the exact opposite.
