Minecraft ban for no reason?

My friend was banned from minecraft yesterday for no reason and since he has not found anything, I ask the question here

He may have done something in chat or in the world. For example insulted or a swastika built. These are Minecraft's new stupid guidelines.

He was probably banned from Mojang.

What exactly did he do before he was banned?

Yesterday we played normal on a server skyblock this morning

No he didn't, we didn't write anything in the chat because we communicate via discord

This is not a server ban but an account ban from Mojang. Chances are you don't have a purchased realm or Minecraft. Do you have a crack version or alts or something. Look what is under "more info". They will very likely explain to you what to do. Google Translate will help you with that.

Then he has to contact support.

It's my friend who was banned and he's been playing minecraft for years and bought it normally in the Microsoft store. With more info there are possible reasons for which he may have been banned, but none of them apply

The account as such has been blocked.

Looks like a not so legal old account, which Mojang has now recognized and disposed of.

Maybe he was on another server and was doing nonsense. Then he can also get a ban on your / his real. I don't think that's a good thing. You pay for a server and then you can't play anymore. It doesn't exist in Java. As far as I know, you can still play together on external servers.

Mojang does not handle requests for exemption, as I understood it in the news.

I think he plays on the Bedrock version (with a Microsoft / PSN account), Alting is not that extreme there. Rather, think that he was banned for insulting, for example. There's also banned.
