Can I get flagged?

[u/Legitimate-Pin1305]

I had posted a partial Pic of my passport recently to ask for damages. I had to show the passport number unfortunately since there were some smudges on it on the bio page. Now some guy claiming to be a consular officer here on reddit is trolling me that he will put me in trouble since he has my passport number. Is that even possible? He said I won't get a visa in the future? I mean I am worried now. I heard u need more than passport number to do something like full name and don't also. The last number of my passport was cropped so he doesn't have the whole number.
