What do you think about “domain by association”?

However, using a domain by association has the main advantage of giving your website a relevant domain without running the risk of a Google penalty.

TheDNA is a non-profit international business association that emphasises the advantages, innovation, and worth of domain names and TLDs. TheDNA represents the domain name industry's interests. Groups, companies, and individuals interested in the provision, maintenance, and sale of domain names make up its members. Organizations like domain name registries, registrars, resellers, and registry service providers are included in this.
