Twitter – Mass-Listing Twitter Users

I am looking for a method to mass-list all Twitter Employees to a public list of my own.
It sounds like it should be within their TOS here is what I got from their Policies:

Spam: You may not use the Twitter service for the purpose of spamming
anyone. What constitutes “spamming”
will evolve as we respond to new
tricks and tactics by spammers. Some
of the factors that we take into
account when determining what conduct
is considered to be spamming are:

• If you have followed a large amount of users in a short amount of time;
• If you have followed and unfollowed people in a short time period,
  particularly by automated means
  (aggressive follower churn);
• If you repeatedly follow and unfollow people, whether to build
  followers or to garner more attention
  for your profile;
• If you have a small number of followers compared to the amount of
  people you are following;
• If you add a large number of unrelated users to lists in an attempt
  to spam a service or link;
• If you have attempted to "sell" followers, particularly through
  tactics considered aggressive
  following or follower churn;
• Using or promoting third-party sites that claim to get you more followers
  (such as follower trains, sites
  promising "more followers fast," or
  any other site that offers to
  automatically add followers to your
  account);

This point

If you add a large number of unrelated users to lists in an attempt
to spam a service or link;

does not seem to include Twitter employees. If someone knows otherwise let me know.

The method should have all/most of the following requirements.

• Services that follow Twitter's TOS
• (Page scraping – I am not so sure about)
• Quick and simple (I could do it in 15-30 mins but thats just wasting time and getting distracted everytime I open a user's profile)
• Ability to append to existing list (I started without the employee page from @ev replies to other users)
