Software developers are not ignorant of piracy. When you use a "better" or shared license key found on a forum, it is usually a key that has been circulated thousands of times. Developers maintain a database of these leaked keys. When the software connects to the server to verify the license, the server sees it has been used 5,000 times and instantly blacklists it. One day, your software works; the next, it reverts to the trial version right in the middle of a big project.
