Is there a safe way to delete a hashtag from my Mastodon instance?

[ThomasLeister]

Some of my users have used a hashtag that was spelled wrong. Now the problem is that the misspelled hashtag is suggested when composing a new message and if you don't look closely, you choose that hashtag.

I'd like to make Mastodon forget about the misspelled version of the tag. Is there any safe way to do that? Without corrupting the data in my database?
