I have reactivated an account after several years just two days ago. I have only played one game and only sent 4 typed messages in the in-game chat. Those messages are completely innocuous and unreportable. In one, I simply apologise. In another, I tell everyone my brain broke. In another I said "push to pass for 12th in a daily lol?", which is an extremely tepid criticism in the form of a question. One other I forgot but it was 2 words, inoffensive and again talking about myself.

One of these messages was reported, presumably by a disgruntled loser. PSN does not tell you who, which message or any information at all. They claim to have done an investigation, which can only be a lie. They claim to have done "careful consideration", which is also clearly a lie. I know these to be lies because I'm one of the few people who can say they have only sent 4 completely innocuous messages.

I also tested reporting some of the spam/scam messages I have received historically and within a matter of minutes all 6 reports were reviewed (obviously not by humans) and I got a nice little message telling me they had all breached and action had been taken. So PSN is giving cry bullies a tool to bully others and then a nice message to give them their satisfaction of knowing they have ruined someone else's day as well.

After looking online, there are plenty of others with experiences like this and any message can be reported by anyone for no reason at all, and clearly PSN will uphold regardless of the message. Therefore, the advice is to avoid all forms of communication or user generated content on the platform as you are at risk of losing everything. In addition, NEVER buy anything digital, because you are liable to lose it.
