What's a company secret you can share now that you no longer work there?

Worked for a Gaming Hoster. Critical informations where hidden in small texts everywhere just (we) couldn't get sued. VPS would get "corrupted" when not used for a period of time, just so we could replace it with a new server. Backends were not protected. You could replace the executable with something malicious and get access to the server. Some more specific things i can't name or it would be clear which hoster it is. NEVER trust a gaming hoster which have access to you server files..
