How to X-Trace Ima Troll?

[?]

This Usenet troll lives in London, but claims that he's in Chile this
week.

A motorcyclist of *normal* interests would be bragging about the
scenery in the Atacama desert, but Ima Troll is spending his time on a
computer flaming anybody he can start an argument with.

He apparently used a Yahoo email address to get an account with
Individual.net, a service of the University of Berlin then let the
Yahoo address expire.

In a later message, he's telling me to read the headers, and now the
path indicates that his postings are also being routed through
glorb.com (in Ohio) and erje.net (in the Netherlands) as well as three
other servers in Germany.
