When I worked in the Intelligence Community I had to go through multiple FBI investigations and polygraphs. Every single one of them asked me about laws I may have violated in the past. One of the agents even said (paraphrased, of course) "Maybe you downloaded some movies? It's illegal but many don't realize it and probably most people do it".
Pirating is one of those crimes that has become normalized. The parent may have realized it was illegal but didn't think much of it and probably didn't realize it would lead to his account being completely disabled.
The trouble with Google accounts and becoming disabled is it can very likely ruin a good part of your life because of how much of your data they hold and there are zero ways to redeem yourself if you did do something wrong and there are zero ways to resolve the problem if it was due to something inaccurate or false (which has happened especially if someone else gets into your account).
