Free Hosting Issue

[ Moderator note: moved to Fixing WordPress. ]

Hi
I am columnist and run an online Urdu Newspaper for my district. http://thebannutimes.byethost6.com/wp
Yesterday I received this email
Hello Valued Customer,

Thank you for using our free hosting.

This email is to notify you your site ………. has used over 50% of its daily hits! your site must be getting popular, congratulations !

A web page is built of many components that each need to be downloaded to make the full page, a ‘hit’ is each of these components downloading, you can see your current daily hit usage on the left bar of your Vistapanel.

All premium hosting accounts have unlimited hits, and unlimited disk space, and start at $3.99 per month, we would recommend you upgrade before you use 100% of your daily hits.

You will also receive a free (.info , .com , .net , or .org) domain name with every premium account !

To upgrade now, simply purchase a new account, then contact us in the support system from your vistapanel to get your account upgraded to premium !.
Now I want to ask that if I don’t upgrade to Premium account so what will happen. Will it block my site?
Regards
