The fact of a case like this 'without clear evidence' doesn't stick in my memory, as other members have said, I've seen a lot of language change accounts and post history, but it's not something that can be taken as negative and vice versa.
Except: as I've seen:

Bottom line: Nothing is suspicious to you, regardless of your posting history, don't worry, it's not in our nature to judge something without valid evidence.
This is a very old story, I have given up all this since I realized that it is risky for the community.
Everyone has a bad past, as long as they have the will to change and stick to the rules, there's nothing wrong.
