Cybersquatters register so many domains and sit on them for so long that the renewal fees alone would bankrupt anyone.
Do they have some kind of special status that lets them pay very low renewal fees? How do they obtain this?
I asked because about a year ago I did a "whois" on an obscure name I was pretty sure no one would have registered and, indeed, no one had registered it. However I didn't really need it and decided not to register it. Then I just did a 'whois' on it again and it turns out a domain squatter grabbed it soon after I did the 'whois' last year. Apparently these guys are getting info from the whois queries and acting on them -- but it seems they'd be put out of business by all the obscure names.
Any technique that enables cybersquatting is a security concern for those wanting to secure domain names.
