A) Did I go too far when I did all the research I described above? Do you yourself often use the Range Contributions tool[4] for looking at vandals' ISPs' contributions?
B) What do you think are the chances that the same person made both the first[1] and the second[7] vandalistic edits? The IP addresses' binary representations are quite different.
Not likely. Both are childish vandalism, but I don't see a connection between them.
C) Why did no anti-vandalism software automatically revert either edit?
Probably those edits didn't match any pattern.
D) When I look at the history[9] of [[Patrick Stump]], I see that there were fourteen edits between 06:51 and 07:03, most vandalism. Yet the vandalistic edits come from a variety of IP addresses and usernames. The IP addresses differ widely from each other. Why is this?
I see more vandalism based on "He died because he divided by zero". Perhaps there was something like that said on the radio and all those people went to the article at once.
E) When comparing two vandals' edits in other situations, is there any quick way for editors to find out both IPs' hostnames, User-Agents, Accept-Charset strings, Accept-Language strings, screen resolutions, and/or IP geolocation results? I do very little vandalism removal, so I myself am not sure.
IP hostname/geolocation can be done by anyone. If it's a registered user, only checkusers can. They also have access to the User-Agent.
G) Wouldn't it be cool if some web browsers or ISPs would tell Wikipedia what a contributor's PPPoE username was whenever the contributor made an edit?
That's probably a breach of their contract. And many ISPs don't use PPPoE usernames, using instead the phone#
