My wiki has a persistent troll who keeps coming back to vandalize the same page in the same way, adding inappropriate text to the image page and replacing the image with an inappropriate image.
I've restricted editing the page to admins only and hope that will help, and I've infinitely blocked the user's three accounts, but after a week or so they come back and I'm concerned they will continue to do so and may switch to editing other pages. In short, it's getting a bit old, and I would love to know if there are any longer-term options in case they return again.
I see on Help:Blocking there's a way to block a range of IP addresses, but I'm not sure if that would help or if annoying but fairly minor vandalism is cause enough for it. Just looking for a bit of guidance.
When blocking, I have disabled account creation and selected the option to automatically block the last IP used.
Here is the page history in question:
