This above is confusing because a lot of players are familiar with English.
If I remove a stain from my shirt I destroy the stain (cause it to no longer exist), if I remove a misbehaving child from the room I do not destroy the child (they can come back later.) Context usually helps (stain vs child) but in the case of a few lines in a Diary combined with the history of how event items are handled there is plenty of room left for questions.
It's also well known that changelogs and Dev Diaries aren't always perfectly accurate in their use of English, and sometimes the information in them isn't perfectly accurate. Players know this and that's why questions are asked.
Is the language accurate? Is it certain the information is correct? Confirming the info, for both buffs and collectibles, and rephrasing to clear up any confusion is more effective than repeating the same phrase or term over and over.
