Once you block someone, that person can no longer see things you post on your timeline, tag you, invite you to events or groups, chat with you or add you as a friend. You block that person for a few reasons:
If that person does that to you, you have the freedom of choice to block that person. I TOTALLY agree.

yes, Facebook temporarily blok the IP address.
You can stop someone by sending message only by blocking that person from your Facebook. Messages will only be stopped when you block the person who is stalking.
This depends a lot on which method that has been used to block facebook. You might get in trouble if you manage to bypass this blocade. I am sure that if you can legitimate your use of facebook, then your network manager will make this possible/available to you.
Block PeopleIf you block someone, they will not be able to find you in a Facebook search, see your profile, or interact with you through Facebook channels (such as Wall posts, Poke, etc.). Any Facebook ties you currently have with a person you block will be broken (for example, friendship connections, Relationship Status, etc.). Note that blocking someone may not prevent all communications and interactions in third-party applications, and does not extend to elsewhere on the Internet.(this is straight from facbook.com under the privacy settings)
When you block someone on facebook they have no access to anything of yours on facebook. If they type your name is search nothing will come up. If you and the blocked person have a friend in common and you post something on your friends page and the blocked person see's it your name will come up as Facebook user. As well when you block someone you are blocking yourself from them aswell. So the same rules apply to you aswell.
