Hi, this was me. That article has a lot of inaccuracies, typos, and general mistakes due to it being a summary of a YouTube video. I recommend instead looking at: The video it is summarizing [VIDEO] My explanation [LINK] The 2b2t wiki page about it [LINK]

Perhaps the most impressive feat I've seen out of 2B2T was an exploit called "Nocom". It began with 2B2T being hit with a lag exploit, then that exploit being fixed in a 3-line patch - that patch subtly introduced another exploit that allowed the author to track the position of every player in the server at all times, down to the chunk. I won't explain the whole video[0], but it details a story of gaslighting, 3 years of player data, and some really really impressive technical work, given this is all over a block game.
