The game also makes a really big deal about all the DIKs phones syncing up. It’s how you share all the proof about Hell week. Whomever leaks the video of you and Jade to Burke had access and it isn’t insane Vinny was never removed. If Vinny isn’t directly behind stuff he’s in cahoots with Nick who’s doing all this.
Nick is too obvious. It's basically on the same level of a red herring as the jocks doing it. Someone that is doing such a campaign is not going to be so stupid as to leave ONLY his room clean. If either Nick or the Alphas did this, it would the most boring conclusion, obvious stuff are always boring.
For the DIKs, the one that would make more sense is Jacob, but still... dude was beyond pissed when his drawing were destroyed.
Same for Vinny btw, he never bothered returning to the frat to sell anything. Him doing such stuff makes no sense. The only point of this is trying to hurt Quinn business, which also don't make sense since Vinny don't appears to be bothered by Quinn until she stole his customers. But he is a way better choice than any of the DIKs for this.
Could be the Nerds. Tired of all the persecution the DIKs did on them and wanted some revenge and used the Alphas as scapegoats. Both Sally and Karen frequent DIK/HOT parties. It's not farfetched for the nerds to hack the DIKs laptop.
Could also be someone from Rusty's family. The house was theirs and the camera has been there for a long as time, so someone could have set them up from the get go, they are rich as fuck so they have the tools for it. Also, if MC is actually a Burgmeister, that would make even more sense, since Lynette's family probably hates Neil and MC since they could see them as the ones that killed Lynette AND the attacks started when MC had arrived in the uni and pledged the DIKs. This one is my personal favorite for now actually.
Lastly, could be someone we don't even have met yet. And we will get a whooole backstory about why this person hate the DIKs so much. It's the most safe choice thought, don't really like this one.
