Alternate Titles being deleted

https://www.imdb.com/title/tt33052017/ 

This title was billed in the TV listings as "Your Kitchen: 60 Years of Fads and Gadgets", but was actually broadcast on TV under the title "Your Kitchen Through Time", which is what appears on-screen.

For some reason this is a common problem with documentaries made for Channel 5 in the UK, and has been for years - almost every single non-fiction programme made for the channel will be broadcast under a different title to what has been advertised. In these cases, I always use the on-screen title as the primary title, and submit the other as an Alternate Title with the attribute "TV listings title", and this one was no different.

However, returning to it later, I notice someone has not only changed the main title to the listings title, but actually deleted all of the correct Alternate Titles; this means that they would have seen those titles with the attributes and therefore known what they were doing, so this isn't some innocent mistake. To confuse matters further, they seem to have removed the poster image I uploaded and replaced it with one that uses the TV listings title.

I have submitted corrections to change the titles back to what they should be (although I frankly can't be bothered to re-upload the deleted image):

Title submission: 250108-103926-055000

Alternate titles submission: 250108-104026-440000

Please could some measures be taken to stop the same person committing the same act of vandalism in the future? Many thanks.
