Re: It's typosquatting
There are two separate problems with this.
First, if you want to implement this, what are your criteria for registrations that should be refused? Is it any domain name that differs from any existing one by one letter? That will create lots of false positives. It also won't prevent one of the most common methods of impersonating a domain, sticking something on the end. Tgeregister.com might be blocked, but what about theregisteritnews.com? If you try to prevent that, then you've granted whoever gets there first rights to so many things, because if I want to have the name theregisterofsomethingelse.com, that might be completely reasonable. If you're going to require something, you have to be specific about what it is.
The second problem is that, although that was sometimes in use here, another popular tactic in propaganda campaigns is to create fake outlets and then ascribe to them membership that they don't have. For example, in the United States, radio and terrestrial television statements are identified by call signs beginning with W or K. WUSA is a Washington-based television station and has a website. WUDA is a completely valid call sign that happens not to be assigned to anything. It's also a completely valid acronym for anything else, so you can't just prevent that domain being registered. It would be easy for a propagandist to set up a website and pretend it's a television network, and unless the registrar is visiting the site to police its content, they aren't in a position to prevent it.
