I am glad that you started this topic, I don't do future trading but the trading analysis is almost the same, can you mention few mistakes you learned like you think every new trader would be making them, Mine was not to setup TP and SL and I was to doubtful about the trades when in past I used to do, and I panic every time I saw loss, I learned if we see a trade making huge loss don't add more funds to it instead exit the trade with some funds left instead of losing all.
DYOR is not a type of disclaimer that should be given or taken into account by a specific group of people it has nothing to do with your expertise it's for the funds, as if someone is risking his funds on someone else analysis he should be smart enough to double-check the entry and risk management precautions. Honestly, no one can be blamed for someone's loss the only one who can be blamed is himself.
There are some investors who might take things for granted like some analysis that the OP will share and the reader take it as granted and afterwards he started to blame him so make himself secure from such blames writing these four words is not a big deal IMO what you think, BTW what's this TYOR it's my first time hearing it or I am forgetting about it.
