Before reverse proxies were around, a semi-common method of load balancing was to redirect users to a different server, as noted by WWW2, WWW3, and so on.
Unless your bandwidth is exceeding the physical capabilities of a dedicated server, you don't need it. And even if you are exceeding your server's capacity, it's a far better idea to use a reverse proxy like cloudflare.

Thank you for your answer, I'm still not completely satisfied with that answer.
If that is the method for load balancing, why google indexed this. And i don't think people do it because they don't have enought money to buy server or bandwidth.

Because they did not properly set their rel=canonical tags.
You cannot just throw money at a server and magically make it grow more powerful, after a certain point the only way to expand is to get a second server. And since that second server has a different set of IP addresses, a load balancer has to point traffic toward the secondary server.
Keep in mind that this method was popular in a time when SSDs, 32-core servers, and GB ethernet simply didn't exist at any sort of reasonable price, and the only sites still using this today were built 10+ years ago.

See that pic bro.
I don't think all these people randomly do that.
I guess they do that purposefully, example: google deceit, or something related to SEO

Maybe they just think it looks good, or maybe their admin made a typo that was never corrected? It doesn't give any SEO bonus or avoid Google penalties, though I guess it did get them some free publicity by you posting their domains here.

This is largely speculative, but generally each of the www'n's is simply a different web server, which a given user has been routed to either manually (for example all images might live on www2, etc.) or by some form of up-stream round robin system or load-balancer, both of which tend to use some component of the end user's IP address or similar to ensure that a user's session will remain on a given server.
Incidentally, more modern implementations will hide the existence of multiple servers behind a single 'www', so that this is less visible/intrusive.

The above thing is done purposefully and the reasons would be -
1. Stored all video on one main cloud server & then embedding to various child sites.
2. If you watch and spect each site then you'll figure out that guy is having variations as per the categories (i.e 1 site is showing drama, actions & whereas the other one is for TV series).
3. WHY? It will help to rank just with proper on page optimization with the keywords using appropriate tags & categories.
4. WHY Multiple but? Simple, if he ranks 1 site then space will come for other 9 competitors. Acquire all the 10 spots
so that ads revenue will come to a single owner.5. Perform A/B Testing - Will try different ad networks and figure out which ads are giving more revenue. If you are running a single variant then it would be a bit difficult to perform A/B Testing.
