The degree of harm that vandalism is considered so because of the state of the profile.
If one knows for sure (which I did) that a page was to be deleted for breaking rules, then there is no harm done by changing the page.
This is because it isn't a profile in the first place, it's like if someone posted nothing but a bunch of pictures for a profile.
Someone then changing that to "Someone delete this" isn't vandalism, because it's not a profile, the same thing applies here, it was clearly not a profile and very obviously was going to be deleted.
Any precedent set would be "Profiled that are confirmed for deletion may be changed as they are being deleted", which doesn't actually change or hurt anyone.
There is no degree of harm, only fun to be made.
