No it was definitely about Null. He is absolutely seething about being left on read and now is trying to remember anything that Null has ever told him privately to try and get a hit in. Ofc he has no receipts and Null is smart enough not to share anything of importance with a drunk fool like Rekieta to begin with. Nick just didn't understand that what Null told him about trying to prevent CSAM uploads isn't an admission to being a pedophile who stores CP on his harddrives or whatever he thought hashing meant.
I'm sure he also has some of the many people who don't like Null in his DMs trying to feed him rumors and unsubstantiated bullshit. He can't post any proof cause he doesn't have any. That's why he has to do the whole "What if SOMEONE is doing these things hypothetically?" It's almost like he's doing everything he is accusing KF of doing to him to Null.

Drunken bald hypocrite that he is.
