Social bookmarking question

Hi warriors..
I have already subscribed to many social bookmarking sites and as a profile name i put my Blog name.I am going to make a natural profile,with a lot of friends and i will bookmark some of my posts.

1)Will you think that i should change my profile name(which is the name of my blog),because i think it will look a little spammy to post pages of my blog with a profile name being same with the name of my blog(but i will build a natural profile and i will bookmark other sites of course,because this is the key).

Again i do not know if it looks spammy,but if we take point that google know the ips of all the interents,this means that google knows who owns every acoount at these social bookmarking sites.So google knows that these social bookmarking acounts which is full of posts of the same blog owns to a specific blogger who try to promote his blog via social bookmarking sites(which i dont think google consider it as spam).So if we take point the above sentence it doesnt have sense to change my profile name to my nickname.Right?

2)Will you advise me to bookmark all of my new posts to all social bookmarking sites immediatelly(by hand or even with services like Onlywire or Bookmarking demon etc..),or it will look a little spammy(i should post for example 70/100 of my posts and not immediatelly)?

To tell the truth i prefer natural ways(for example post my today blog post to the first 5 social bookmarking sites and the tommorow blog post to the other different social bookmarking sites)

3)I think that google only will think my acoounts as spam if i make for example 2-3 natural accounts from the same ip.In this case google will think i am a spammer(and it is logical) as i will try to cheat.Right?

*When i mean social bookmarking sites i do not speak for facebook,twitter and google+ as in these sites( my fb,google+fan page and twitter) i will post daily my daily posts and i think it is a nice move(as it is a fan page!) My profile name to fb,twiiter,google+ is my blog name!
I speak for Digg,stumbleupon,reddit,propeller etc...
