Questions about facebook timeline - security concerns?

[Super]

If I delete my facebook account (as I dont agree with the new timeline feature) will interactions people have had with me over the years still show up on their timelines even though I no longer have an account?

Also, if I did decide to stay on facebook but blocked certain people would interactions that I have had with them still show up on their facebook timelines and on mine?

Basically there are people on facebook who I have blocked on facebook and I dont want my name to suddenly appear on their timeline or their name on mine, surely if someone is blocked then it should be as if you dont exist to each other on facebook?

I currently have my profile deleted but will reactivate it if it would be better to have it active but certain people blocked to limit my interactions with someone appearing on their timeline.
My concern is I dont want an abusive ex to suddenly have me pop up on his timeline when he is blocked

If someone is blocked, they cannot see your profile - assuming you have had the common sense to make it visible only to friends.
It would seem you are not emotionally suited to social networking. The definition of social networking is the sharing of news/pictures/videos etc.with your friends. The timeline is simply a jazzed up way of doing this. There are no security issues, unless of course you have your profile totally open to the world
