In my case all sites share a template and are similar in code, use the same url structure, and number about 100 they are also all casino sites. So I don’t know… maybe I picked up on something that doesn’t exist.. maybe there is no penalty, but I swear to god I have heard this before 
I heard back from my act. manager at godaddy : For about 4000 a year I can host 100 smaller sites on godaddy and get a separate IP address on each site.
Mostly was just curious about this topic.
Thanks.
