Banned from community, questions.

Hi,

I saw that someone replied to one of my topics, and I wanted to react or reach him back. But I've saw the following :

I suppose it's only the Network community ? (where the post was hosted ? )

I've discovered the modlog

https://programming.dev/modlog?page=19&actionType=ModBanFromCommunity&userId=1227688

But this user seem to have a lot of activity :) So I don't find why on Network he was Banned ?
\ is there an easy way ?

Thanks.
