This is really very cut and dry: GoDaddy's terms of service prohibit use of their services for harvesting PII without express consent from the person whose PII is being collected. The anti-abortion activists' site openly invites the public to doxx 3rd parties, and hence violates the policy. The anti-abortion site is not functionally that dissimilar from something like a site that allows doxxing ex-romatic partners or the like, and both represent low-value forms of distasteful speech that frankly, no private service provider ought to be obliged to faciliate.

While GoDaddy could be politically or morally motivated here, this just seems like a fair application of the policy.
