You must make a regex that matches everything except itself. For example, PPCG must not match PPCG, but must match everything else, like something, PPC, and PPCG!.
Surrounding slashes are not considered part of the regex in flavors where they are usually part of the syntax. The same is true of all delimiters.
The regex needs to match the entire string, not just a substring.
You may choose your flavor, but you can't use a flavor newer than this challenge. Please pick a flavor that is easily tested.

You must make a regex that matches everything except itself, including delimiters. For example, /PPCG/ must not match /PPCG/, but must match everything else, like something, and PPCG!. If your language allows compiling regexes from strings, you can argue that the quotes are your delimiters, and use those. You must use a common regex flavor (eg. older than this challenge.)
