No.  Don't add speedy tags at all if you are incapable of making a simple decision.  The nn-bio tag is for vanity pages.

Even if you are suspicious there is still Google or special:whatlinkshere to confirm your suspicions.  But you said gibberish  are you then incapable of parsing simple English sentences?  — Dunc|☺
