careful about putting a page on "Lock" mode. There could be other things about the page that need edits.
Side Notes are often helpful with suggestions.
I could mention that Zendaya's page received an unfortunate "Lock". It's confirmed by directors that her character died in 'Avengers: Infinity War', but people argued and it went on "Lock" with the entry removed!
Please provide IMDB listing of the actor as well as the IMDB listing for the film the actor died in. From what I remember it wasn't a real film and someone tried to include a listing of Angelina Jolie from it which was a bogus listing as well.
Should Dove Cameron's page be locked if the persistent vandalism on the page continues? As you've probably noticed, an anonymous user has been adding fake death entries for Death Note, which Cameron does not appear in, and a 2019 version of Carrie, which does not exist. Other users have proposed preventing unregistered editors from making edits, but if that's not an option for this wiki or at least this page, the best option is just to keep it locked to prevent the continued vandalism.
My primay concern is that once the pages are locked the user might go to other pages and start doing the same thing which is what happened after I locked the pages that they were initially messing with. This could continue and even more pages would then be locked. I've been blocking the IP addresses, but they continue to find new ones. (Not sure how that works) I don't mind blocking and making the changes every single day if necessary as I check those pages every single morning and will continue to do so.
Thanks for your help. Dove Cameron and Hailee Steinfield appear to be his main targets, although it wouldn't surprise me if he also starts vandalizing Dakota Fanning because he's falsely claiming she dies in Cult of Chucky on Steinfield's page. He must be using some device to change his IP - a VPN would be my guess - so we probably just have to wait until he has his fun and gets bored with vandalizing the pages.
