Question about domains on same private name server effected by black hat methods

I have a reseller account with hostgator with a private name server. Most of the domains hosted are white hat, but I wanted to do some black hat on 2 of them.
I read a while back that google may block other sites that are on the same server - is this true?

I also have an adsense account that is 4 years old that I have been very careful with - wondering if the bh on other domains ( no adsense on them ) will have any effect on
the "permanent" domains with the adsense.

Maybe I have been reading TOO much but.. wow.., I'm paranoid about everything right now. I feel like google is under my bed at night :nervous:

I guess my plan is to work on the other long term, permanent projects, and do some faster (relatively) work on 2 projects.

Thanks!!!!!!!!

Although it may not necessarily be an issues, its always best to host your domains on different hosts.

I felt like that was going to be the answer - thank you!!!!!!!!

It doesn't matter until you interlink those two websites.
