Will they close my account if i do not get any clicks or page views for a long while? If yes then will i also be black listed?
I dont think your account will be closed , why did you sign`up with adsense if you know you will not recive clicks yet ?
unfortunately yes. if you dont have any impressions or clicks for a long time or takes you years to make $100 threshhold, your account is at a risk of being closed. lot of accounts have been suspended due to low or no traffic for long time
Websites with low or high traffic have the right to exist with google ads. Google has no headache with your traffic and click, provided, you don't violate their rules.
