For writers' portfolios, no the pieces included don't have to follow the app limitations! They can be any length, any rating, etc.

Basically we're just expecting something like an ao3, Google Doc, or carrd/other hosting site to check out more writing if we decide to dig a little more past the 3 samples provided. However, we strongly urge making the 3 main samples your best work as not every mod will look over portfolios! They're just there in a "just in case" situation if mods feel the need.

We hope this helps!
