site:mydomain.com does not return any results anymore :/

Hello,

One of my 2 weeks old site got de-indexed from google, before
site:mydomain.com was returning around +15 results, and it was a keyword domain on serp 5 for 4-5 days continuously.

Scrapebox was used to promote, i was not gonna be sad if google just moved my serp to 100000 but also my index is gone, it is like my site is not existing or existed ever on google


So is this what people do talk about `sandbox`? or this is more serious shit?

Any idea if the domain may re-appear and such thing is usual or once the site got de-indexed by google, there is no way back around?

I worry because i used the same adsense code in it which i have been using for my white hat sites too and i dont want them to get affected or something

if you are experienced about this situation please enlight me

Thanks

is it what they call sandox or it is directly a ban?

do sites who are in sandox, return any result when u search as site:domain.com
?
