>- Discourage users visiting via the IP Address, adding that to favorites, sharing it, etc. Making it difficult/impossible to migrate That's not a reason to reject. That's a reason to issue a redirect. No regular user that would make the mistake of bookmarking an IP instead of a domain is going to know how to use an IP to get there in the first place. >- Make it harder for databases to associate that IP Address with your site (for user privacy). You're misunderstanding how these crawlers work. They don't just walk all IP addresses because that's a good way to get an abuse letter and because if there is no redirect to a domain they don't get the domain. These crawlers just follow links like any other and log the IPs they resolve to. The only way this helps user privacy is if there are no links to your site anywhere on the internet.
