Really a BAD day! A big loss~~

I am dreaming of having a PTR site for long,and months ago I save enough money to buy a domain and a full year host on Lunarpages.
I spend most of my time to make my site beautiful...when all things done,I decide to open my site that day.
You know,get new members to a new PTR site is not easy work,and I spend dollars to make ads on other sites.
Well my work was paid,I get 24 members after a week's hard promotion.
However,all things were changed because of host!!!!
That day,I find I can't open my site.Then I checked my mailbox,it is a letter from Lunarpages ....
It said that----your host account was suspended for ever!Because we don't accept the so-called email market site!
All my hard work was gone,you will never know how sad I was then.Before I open my site,I don't know HTML code and basic knowledge such as DOMIAN adn Host.And I spend much much time to learn them myself,And I bought a CC script at a cost of 80 dollars.When my site opend that day,I feel it as my friend..
But toady all gone,I have to chage my host and do all the work again.
Why doesn't the host tell me this in advance?Why it doesn't suspend my account at first?And my site is not a spam why you can't treat it equally?
I am really down these days,noy only I just lost a website,but also a friend.
