One site - several domains, how much is such a scheme needed?

Question

Computer networks

Good day!
Starting a project to create a site on a non-commercial topic, I'm interested in the question - how desirable is the registration of not only the main domain (for example, site.ru), but also similar names on other domains (.net; .com, etc.)? Perhaps this can allow organizing load balancing, or am I mistaken in this?
Excuses about: "Who will need to register it in the same way", "yes, there will be little traffic there", etc. I don't want to accept. Interested in the essence.
And in general, will it be possible to somehow influence the "copy-paste" of your site, or domain name? For example, will a complaint to the hoster give anything, or in extreme cases, the court (although the site may be abroad)?

Answer 1

Load distribution will not give any if you link all domains to one hosting - a domain is just a name by which you can find a site so as not to search by IP. Load balancing requires clustering and balancing.
It all depends on the audience and the direction of the site.
If the site is being developed for a local Slavic audience, then, as noted above, you can additionally take a domain in the Cyrillic zone for the convenience of dictation and, as they say, "this is the mainstream."
If the site is planned as an international one, then you can register domains in national zones and send traffic from them not to the main page, but to localization pages, where, for example, immediately set the language, addresses of regional representatives, and the like. In this case, it will be more convenient to redirect primary traffic to auxiliary servers to offload the main one.
There is also a third option: when companies post their names in all popular zones at once, so that later they do not compete in courts with patent trolls who will register all sorts of "google.rf" and will trade crazy sums for buying a domain from you.
