Is beethoven97 a hacking bot?!

First thing I really appreciate he(beethoven97) makes the tests stronger and rearrange the standing correctly.

I just wonder how do he do it?

A picture from Educational Codeforces Round 130 (Rated for Div. 2) that showing the number of hacks he made until the time I wrote this blog:

The python3 solutions without fast input were basically ... hacked until they TLE, he ran the same test over and over again on the same solution (since runtime is 1900+ ms and time limit is 2000 ms) it may sometimes randomly TLE

That should explain why so many hacks ?

I think he might have used a script or something to run some generated tests against borderline TL solutions
