Unfortunately, the way you phrased that question is 
rather "journalistic" and in BT, as in most large companies, 
employees are forbidden from answering such questions without 
having the answers vetted by various Public Relations 
and Legal departments.

Fortunately, published material is exempt from this rule 
so Googling for an article I found this:
which contains the following:

    Using data from the system, BT's abuse team can cancel 
    rogue accounts linked to spammers or add offending 
    IP addresses to blacklists.

    The system also allows BT's admins to contact consumers 
    whose compromised (zombie) PCs have unwittingly been 
    made the part of the junk mail problem and provide advice
    on cleaning up their systems. 

Seems pretty clear to me. We take the issue of botnets very
seriously and we have invested money into tools which automate
some part of the process of identifying and removing bots.
Just what was the point of your query? Do you have some issue with 
traffic emanating from BT's network? 

I admit that we are a rather large company with several
rather widespread IP networks, nevertheless, a simple
RIPE database query of "BT" does lead to more than one 
abuse contact and also lists several real people who 
you could contact directly if you need to coordinate activity.
