https://serverfault.com/questions/732948/number-of-domains-under-a-registrar-how-do-you-determine-this

I am getting more than a little irritated by the `Hold` on a perfectly reasonable questions that is marked off-topic with no explanation for how a particular rule applies.
	
*This question does not appear to be about server, **networking, or related infrastructure administration** within the scope defined by the community* - 

I needed to figure out who the big registrars are and one way is to take a look at their client list. Also a good way to filter out the nasty creeps.
Yet this question was put on hold in what appears to be a very arbitrary fashion.
