Please refrain from talking out of your ass from now on. Blizzard does not scan anyone's .dll files, never have. What you may be TRYING to refer to is the fact that D2JSP does(or once did) inject a .dll into Diablo II's memory, which allowed them to detect it's use.
Just use D2JSP people, you're not going to get banned, as Blizzard no longer cares about this game. They have newer games to worry about.
