Please 'like' my facebook page - a rant

How many times did someone you didn't even interact with  -- on facebook or elsewhere, sent you a friend request, just to immediately post a link to his or her facebook page, asking to take a look or 'like' it?
Does that annoy you as much as it annoys me?
No, seriously. I don't have a problem with people building their pages and if a fan happens to like it -- fine by me.
What pisses me off is the cheek people have to pester me with their generous offers on my wall. I always feel like I've opened the door to someone I just met and, without saying hello, he comes in to placard my walls and leaves flyers everywhere, just to bugger off after that.
I don't like that sort of behaviour. Facebook has become more and more a pain in the backside and people only use it for promotion instead of communicating with each other. Every time I get a friend request, I check the person out to see if they plaster their links on the new friend's wall or not. If you look at their own pages, it's often full of links to their books which are available on amazon, smashwords or even on the moon. Despite having 2548 friends, they don't interact with them. Gee, why don't you just tattoo the title of your book in bright red on your forehead and walk through the streets? Would get you certainly more attention than get on fellow writers' and authors' nerves.
As you probably have guessed by now: I'm allergic to it.
You know, I wonder why those people take themselves so damn seriously? Who do they think they are, written a book, sold three copies and feel the need to force their fan-page down other people's throats?

Do they not understand that begging to take a look and like their page is not only the pathetic attempt to gather some better looking figures underneath the like-button, but also preaching to the choir?
I used to have a page for my novel No Wings Attached and I remember that I asked my few friends I had back then to 'like' it. I think I ended up with something around 26, oh dizzy heights of stardom.
I'm trying to understand what the point is, because unless you have hundreds or more people following your updates, it's just more work for a site nobody's interested in. How many of those who've been asked to 'like' the page actually go back for a follow up? I place my bet on 1%. 

I have you know that I'm going to build one in the near future and be it only to take revenge on all those authors who thought it's appropriate to leave their rubbish in my living room. And I'll leave a link three times a day, every day.

There, now, I feel better.
