The thing is that people quickly realize your "bugs" come from the pirate version, a famous example is CDRWin which toasted CDs with invalid serials. Everybody knew the original version didn't have the problem. You need to be clever about it. Another example is video games that are impossible to finish when they are pirated. The Operation Flashpoint game displayed a message "Original versions don't fade" on pirated versions and ceased to work.
