Can shared webhosting affect my SEO ?

Hi All, 

This is something that has made me head for a long time.

If I share with other 1000 users the same IP address in a shared webhosting, and some of them have bad practices that mark our common IP with a low page rank, I am affected, too, isn't it?

So, is there a solution for this or we only can hope that our services manager discover those user and get rid of them?
