Recent versions of Mytob do the same thing. Mytob, if you remember, is 
R[x]bot + Mydoom. It appears that Zotob is just the Mytob code with the 
Mydoom code removed and replaced by the MS05-039 spreader, and that 
both codebases are maintained by the same person. Doesn't explain his 
motives for blocking those sites, but does explain why it is in the 
Zotob codebase.
