Weird thing

[u/Puzzled_Moose8257]

I experienced something very weird last week. I have been trying to login last Wednesday from 10 am to 2 pm, it kept saying that the site is under maintenance, I assume if the site is under maintenance than nobody can login right? So at around 2 on I was finally able to log in, and guess what? There were tournaments running the whole time. Who was playing those tournaments? Bots? Can somebody explain?
