Can you author a post that contains not a solitary showing of that symbol fifth in rank out of our 26 script-signs (found amidst "d" and "f")?
Your trial, should you try it, is to author a long (and also normal-looking) forum post that cannot contain a fifth symbol of a distinct group of Latin pictographs.
Limitations of this forum topic:
Acts usually cannot occur historically
Our communication cannot contain translations for Spanish “la”
Many forms of “is” cannot occur
Much of our vocabulary is in violation of our axioms
