It depends on the IM messenger, but most of the time you can just right click on the contact you want to block, and there should be an option to block/delete contact.
The 'key block'
There are some ways of doing this. Finding out the website's IP address and putting a block on it can block MSN. There is also some software available with parental blocks, and you can list MSN as one of those that would get blocked.
Yes they can, but you will just show as offline They can see your old personal message, the one you put on before you blocked them. But if you change it they won't be able to see it. Your status will be offline to them.

They can't see any of your information such as bio, pictures, etc.
All they have to do is look to see who is online if you are using Aol it is more than just easy...I have had it happen to me. If it is someone you don't want then block them from iming you.
When someone is attacking your face, block high. When someone is attacking below your waist, block low. When someone is attacking your body, block in the middle. For explanation beyond that, see an instructor in person!
If You Block Them From Calling You You Can Also Block Them From Texting You ..!
