To block someone visit their twitter page and click on the "Gear-wheel" icon and select block "user"
Remember once you block a twitter user,
1. you will automatically be unfollowed by the user you blocked
2. you will automatically be removed from any lists the user may have added you in
3. If the user visits your twitter page, it will say "This user has blocked you"
4. Blocked users cannot follow you again, unless you un-block them
5. You can un-block a user from their twitter page, well if you forget their username, thats a spot of bother. (You can use third party tools to un-block users)
PS: Threat tweets? Not sure.... I'll ask Assange and tell you
