It´s a known thing.
Very bad Google is helping them!

Then your domain disappears from the SERPs, you just have to change your domain name and after 2-3 weeks you get your rank back slowly.
Of course, inform Google about your domain change.

If you are lucky, that´s it. But maybe they will request the de-indexing another time and a 3rd time
It´s a cat and mouse game you eventually can win, because they just give up after few attempts.....
But it´s stupid because you "lose" good domains who keep being de-indexed by Google.
More or less they are burned.

If you want to know more about it, you have to contact Thommy.
He was helping many webmasters from a German adult webmaster forum back in the day.
He knows best how to deal with de-index issues and how to get the rank back for your site in case that happens!
