I noticed Sparkle_Twilight for a long time, when I was not a problem solver at all. I just randomly opened some "good problems" from a problem list, clicked the status button, switched to sort by code length, and bam, Sparkle_Twilight.
I was wondering how could a single unrated account pass so many problem, you can find this accound easily on the ranking of problemset and it's on top2. And I watched their submissions, wow, obviously crawled from others' code. All passed at once (except some CEs) with different styles even languages. So I confirmed that this is just a shit bot account hanging on the leaderboard.
So I want to know, why there is Sparkle_Twilight? Even if bots are allowed on Codeforces (of course there are other bots), but what's its original purpose? It's not a remote judge bot like vjudebot or luogubot, it only does exercises without positive feedback. Is it just to look good on the leaderboard?
The remote judge bots don't need a formal username, maybe Sparkle_Twilight is a remote judge bot.
remote judge relies to cookie(JESSIONID) not username.
emmm, Sparkle_Twilight isn't a remote judge bot.
Mike should ban these bots(like Sparkle_Twilight), there are wasting CF judge resources.
Without them, all submissions will have a better judge speed.
I think remote judge bot shouldn't be banned but limited, and of course methods like remote using our own account might be a better solution (like what Luogu did).
It's just a way to, well according to my coach, prevent us from easily visit the internet and steal solutions,
so he was trying to build his own remote submit bot but failed.Have you ever seen a remote judge bot who can get AC at their FIRST submission on EVERY problem with the almost SHORTEST code at that time, and don't resubmit when they chose a wrong language?
