What happened with my clicks?

Next day i just added my sites in allowed sites,

 

But one thing i want to clear, My brother is also running some sites, one image hosting, and one an entertainment site and forum, his and my IP address i same because we are using one same connection, and he received intimation from google about wrong clicks, my question is
Is it harmful for me too, because of same IP?

 

use nice keywords like ebooks,finance then u get more mny

 

i think it is invalid click and they clicked public ads.....

 

Its hard to get 370 Clicks from 5k impression.
Some of them are invalid clicks.

 

Well i just started a video blog with a sub-domain at http://apnimastian.net/blog/.
Is it need to add sub-domain in allowed site too for showing adds, apnimastian.net is added in allowed sites.

 

still waiting for my answer
