Only SE devs can blacklist a tag, for obvious reasons. The procedure of blacklisting a tag is exhaustive and takes time, as explained by [this answer][1]

Burninating a tag simply means that a tag is not needed **in the current time**.
But that doesn't mean that it should be disallowed forever. A word that is unwanted one day can become the subject of many questions later. 

Tag blacklist should only be done when we are sure that such a tag will never return. Blacklisting generally means that a tag is *bad*.

That said, there is no need to blacklist a tag just because it is a typo, it is unlikely to come back, and you don't want to annoy the devs with such requests that don't really help the site in the first place.
