Well there are a lot of reasons

BUTTTTT i will explain 3 ones

Stealing content, this polish guy "nieśmieszny" [not funny in English] has another channel "zabawny" [funny] but he is actually stealing video ideas from 1 creator called "ChainsFR" AND HE BASICLLY STEAL HIS STYLE AND VIDEO IDEAS

Ok, but what about the 2 reason? Well here am I to tell you

There is a polish youtuber named "Cyborg" and she has problem with ears, she wasn't posting for an years, but she uploaded a video 2 weeks ago with no sounds and the text explaining what was going on

WELL GUESS WHAT NIEŚMIESZNY DID...

HE FUCKIN MADE THIS BULLSHIT

(The thumbnail screenshot credit: FatherRikuru on youtube)

SHE DIDN'T HAVE FUCKIN GREEN FACE but he quickly changed the thumbnail (he also did with another youtuber, but I don't remember which one)

And the last reason

Nieśmieszny is also saying FALSE INFORMATION ABOUT TECHNOBLADE WHO DIED FROM CANCER

The title was "Technoblade is alive" AND HE FUCKIN SAID THAT HIS FAMILY IS DOING THIS FOR MONEY

Like... how can be so evil... TECHNOBLADE'S FATHER CRIED AND HE COULD NOT FINISH, BECAUSE IT WAS HIS SON, WHO DIED AND NIEŚMIESZNY TOUGHT "meh, im gonna say his family is doing this for money"

This person is evil... NIEŚMIESZNY... IS FUCKIN EVIL

Rest in peace Technoblade...
