Question about black hat seo on same hosting-website

Hello all
I have shared hosting with HostPapa...and i have 4-5 domains hosted there with them. Each of them is different niche with different content and not related to each other at all...
My question is, i plan to do very black hat seo to one of my domain there, but will it maybe affect other of my domains there since it is on same hosting, because i have one good domain there that is purely white hat so far and doing good on google..if someone knows about this please let me know
Thanks to all!

No, because chances are, you're sharing with hundreds (if not thousands) of other domains on the same server. Where you could get stung is if there is a really obvious footprint linking all your websites, but even then it's unlikely.
