❓ASK – Can anyone complaint for his brand name used by another domain? | Proxies-free

So it is hard. Firstly, do you have a copyright/trademark on the name? If not, I don’t see there is anything you can do.

And then, even if you do, international law is complex – if the name is registered in a different country you might have problems.
Years ago I started a website with the name PAYPAL in the domain name. I got lots of threating emails from Paypal and decided to close the site – but I noticed the site paypalsucks.com remained online – if paypal cannot take down this site then that is clear proof that it is possible to register a domain with someone elses name in it and there is nothing you can do about it.
