or - here is a idea :
1 create 10 namecheap accounts(you don't need real emails)
2 buy one domain from each - don't use whois guard
3 create 10 cloudflare accounts
4 add your domains to cloudflare and point to your A host
Now you'll have 10 different whois data with diffrent ns pointing on diffrent ip's...
You can't get more secured then that!
why would you want to use whois guard and not different owner data if you have multiple accounts and plan on not doing anything fishy?
