Ban for no reason at all? (confused)

I tried to get on today only to get a message saying i was banned, i checked the link it gave me, and it says Syuse has banned me PERMANENTLY, for “Sie sind von VAC ausgeschlossen worden” which tranlates to "you have been excluded from VAC "… I have never had a VAC ban on my account, and I have never cheated, I am extremely confused as to why I was banned, and would love an explanation. Below is a link to my ban description.

Edit- it appears over 70+ people have been banned for the same reason, just today alone, by the same person, all within a a few hours.
