This is a part 2 of my other blog on the Psychotic_D situation. I highly recommend you see it before this one for context.

If you don't care that much, here is a quick recap of what was covered in the other blog before we get started: Psychotic_D had a ridiculously good performance on his friend's (wuhudsm) round. This let many people become suspicious of whether he achieved this legitimately. Then multiple accusations were thrown around and I did my blog doing my own investigation and compiling the most compelling evidence I found. The takeaway was that Psychotic_D was probably cheating along EndlessDreams, who would give him code for Psychotic_D to copy. Psychotic_D would alter them heavily to avoid plagiarism, but it was clear beyond a reasonable doubt that he was cheating.

Well, I finished writing that blog, responded to some comments and was ready to sleep when something clicked in my brain...

Part 1: Wait, who the fuck is EndlessDreams?

I mean, he is the first thing that appears when you open the TheForces group, he must be pretty important, right?

In addition, his solution to E on Codeforces Round 960 (Div. 2) (over the hololgram-sakura alt) was considerably different from the editorial solution. It was also not the kind of problem a random master could do in 30 minutes. Matter of fact, doing ABCD could already give you a red performance on that contest. Also, there is a team on codeforces with the founders of TheForces:

And EndlessDreams isn't part of it! I would assume that someone who made editorials for all the contests from them is a founder!

Well, maybe they are a founder, because on herav_singhhh's blog, there is another founder that is in the submission pairs.

amenotiomoi checks all the boxes! Think about it, if EndlessDreams is an alt and not the real leaker, the main should be higher rated. On top of that, he is supposedly chinese, like both EndlessDreams and hololgram-sakura. All that was needed was some proof that they are connected. The codes presented in the blog aren't that convincing, so I went for the place I forgot to investigate last time.

Part 2: Who the fuck is amenotiomoi?

In the investigation for the previous blog, i went to the TheForces website for the investigation for the previous blog, but i only entered the cf group for it. This time, I entered their discord server. Normally, discord servers have features so that you can link your cf account to your discord account. So I just needed to search for "EndlessDreams" and then...

Jackpot! This guy is admitting to being EndlessDreams. Moreover, looking at his roles in the server, he was a moderator (indicating he had a high ammount of power) and had an international grandmaster role (which is the same rank as amenotiomoi):

However, it seemed like he never actually set his handle to amenotiomoi on the server. I could see him setting it to EndlessDreams but it looked like his account had no discord handle set to it at the moment. I was going to make an edit to the previous blog raising my suspicions when an interesting message came to my dms.

I changed my discord name to "ribbit" and joined.

Entering there, as said by our anonymous fellow, the discord account belonging to EndlessDreams was there. And he was confessing everything.

Part 3: Confession

At first I was scared to be banned and even recorded a video with all the evidence I found before noticing that it was not a server controlled by cheaters, but just a normal server where a bunch of cpers trained together. Some time after the previous blog went live, he posted this:

Well, I guess we found the guy. To everyone that doesn't know how this works, you cannot link your cf account to discord if you dont have access to it. He is certainly the one that had access to the account who leaked E to Psychotic_D

He also confirms that he is in fact EndlessDreams

He later went into more detail of over what happened

He also explained why Psychotic_D had access to his account

I ended up bantering with him a little, but for the story to fit i had to make one more question

...

I guess that's it!

Part 4: The confrontation

After this incident I may have shared the link to the server on another discord server. A bunch of people entered and we had a lengthy conversation with amenotiomoi/EndlessDreams/hololgram-sakura. Some things in it were pretty noteworthy though!

This is what he had to say when pressed on why he did it.

He was also pressed for details on other cheaters!

It was brought up that on a random cf round, another master previously accused of cheating 1_2_3_4_5_9 had a matching code with amenotiomoi: 210895554 210911093

This is what he had to say about it

This "code that chromate00 copied" is a case from 2023 where he supposedly copied a code from the internet for a problem. It ended up being that amenotiomoi was the source of that code. chromate00 has later apologized and reformed since that incident.

TwentyOneHundredOrBust also had a conversation in chinese with amenotiomoi.

Crazy if true.

Conclusion

Well, this has been a rollercoaster. It is kind of crazy to think that if one strong competitor wants to leak solutions to all problems they can just destroy the competitive integrity of competitive programming. I really hope that amenotiomoi and Psychotic_D reform to some extent, but their account should definitely be banned. Thanks to everyone who helped me with the investigation and everyone who read this blog until here! I'm probably going to sleep.

By the way, amenotiomoi did send an ominous message in the middle of all the other ones

I guess I won't be awake to see it, haha.
