On DALnet, the team responsible for handling botnets,
exploited/compromised hosts is the Exploits Prevention team. The
abuse at dal.net address is for general abuse issues - the mails are
read, and forwarded on to the relevant teams. The quickest way to
contact the Exploits Prevention team is through our online form at
http://kline.dal.net/exploits/contact.htm. Reports submitted through
that form will get a quicker reply/resolution than those emailed to
abuse at dal.net.

You can also connect to DALnet and contact any member of the Exploits
Prevention team directly. The nicks of the team members are:


Obviously, if there's a botnet operating from our servers, we don't
want it there. The sooner we hear about it, the sooner we can put them
out of business. It took us 5 hours to shut this one down, which is an
excellent response time. I've dealt with ISPs, with dedicated, paid
staff who don't react as quickly. Notifying us through either the
form, or contacting us directly on DALnet, would cut that time down
even further.

Please, don't hesitate to let us know if you find a botnet, or even
_suspect_ that there's a botnet operating on our servers. We take such
things very seriously, and will investigate immediately.
