Issue: Auto-link picks up too short links

A user posted a wiki entry with "I" or "I want to be deleted" as topic name.
After this the auto-link system started replacing i and I through out the forum with the autolink to the wiki entry.
The topic name got changed but it would still link to the "i" original topic name, I had to delete the renamed entry entirely for it to stop using the old name.

Even after deleting the old name, the previously autolinked entries would still show "i" with a link to the old topic that didnt exist.
Is there a way to retroactively delete all autolinks on forum without editing the post/comment and saving it?
