I have a question...]

[sweet12]

I have a number of sites on two servers, in two locations.

Does Google ban a domain and or IP when it sees Spammy stuff??

Do I need to apply for a new IP (some new IP's) if I have been banned.

Another thing is when Google sees near linking (i.e. links from a different domain on the same server) how does it see it, is it an IP thing (i.e. the IP that the domain is pointing to) or a DNS IP thing (i.e. the IP's of the DNS servers running the domain.

How does this effect my sites hosted on a popular host, are all links from sites on their servers seen as near, as they all share NS1 NS2 servers?

Well from my point of view they can ban (and demote) domains, but their are also IP's that black listed as well.
