Admins, is this a problem?

I have a question for the administrators, and those who know the answer please answer me.

Is there a problem if I receive Impressions on old posts?

Since I haven't been very active these days, I don't have many new posts and people are constantly going to comment on my previous posts (which are days or weeks old)

Then I remembered to read somewhere that a person could be banned if they received impressions in their old posts, but I'm not sure about it and that's why I ask the admins and I hope they answer me please
