I think "hijacked item" makes more sense as the label, long-term vandalism to me sounds more like the item is frequently vandalized rather than an instance of hijacking (which could occur multiple times in the history of an item).

A revision of the review scope or indication of changes may be needed to better address what may lead to false annotations for hijacked Qids where the label and description have changed prior to the statement that is being compared. At face value the statement change looks like it is a simple mark as a revert, but viewing the edit history there was a series of edits which changed many statements changing the entire context of the Qid.

Confirmed, the deployed patch is live and fixes the issue.
