Clarification : Mr. X is a orthodox religious Jew. Mr. X has a rebellious phase and violates shaboss. Mr. X later starts keeping the rules again. I'm asking in both cases:
Case 1: Ten people knew about it.
Case 2: Fewer than 10 people knew.
I'm asking specifically in regards to yayin nesech. If a person was known to not be shomer shaboss (i.e. not frum) and he (or she) then becomes shomer shaboss, when would one be allowed to drink non-mevushal wine with them?
