I found an interesting way to prove the leaks are 100% real (Without spoiling yourself) (Also, absolutely ZERO spoilers/leaks on this post)
*JUST TO LET YOU GUYS KNOW, YOU CAN READ THIS WITHOUTH WORRYING, THERE IS NO SPOILERS/LEAKS HERE*
So, for some weird reason (and quite ironic), the episode 9 trailer on the GLITCH Youtube channel only has these 3 audio tracks: English, Spanish and (this is the important part) PORTUGUESE! And of course ya'll know the leaks were with the portuguese dub, right?
So if you go and watch (IMPORTANT: ONLY WATCH UNTIL MINUTE 1:32) the leaked clip with the first 14 minutes of the episode 9 (you just have to watch/hear until around 1:32, not enough to self spoil anything, trust me)
So basically in this part, Jax says: "Now we have nothing!"(in portuguese of course).
Now just go to the official ep 9 trailer, and with portuguese dub selected, at around 0:10, Jax will say this part (It's the part where he starts with "Agora" (in portuguese "Agora" means "Now") so just hear the trailer part, and then the leaked clip part, over and over again, analyzing it, you'll realize something that indeed, the leaked clip is 100% the same as that part in the trailer, so yeah, unfortunately, there is ZERO chance the leaks aren't real.
