Are you seriously defending link farms? Do you use link farms to find information? Do you trust the links on those sites? No you don’t because you’ve learned to avoid them just as you avoid opening email spam.
However, I’ve already agreed that there isn’t a way to determine what is or will be a valid use for a domain. As I’ve said, I think charging more per domain is the best way to free them up.
No, I’m not defending link farms, and I think you know that. I’m saying that the definition of “valid” is ambiguous, and in that particular example, a case could be made that the link farm page provides more value to a particular user than a goldfish site. I’m not saying it’s right, just that there’s an argument to be made.
I don’t think that raising the cost of registration is an appropriate solution. If the price is raised to $100, someone will figure out a way to make $105, and we’ll be in the same situation again. Why not raise the price to $250, or $500, or $1000? When we start raising the cost of getting online, we get closer to the point where there is one level of service and access for corporations and those who can afford it, and another, lesser level for everyone else.
Go ahead and create the most annoying sites you can. At $100 per domain, you probably wouldn’t create as many - and the interweb would be a little less annoying
It would also be a little less useful, and a little less unique, and a little less enjoyable. Personally, I’m willing to put up with some annoyances in exchange for the good things that can come from easy and open access. The people who take advantage of the system will just find a different way of taking advantage, and the people who will be hurt will be the people who weren’t part of the problem in the first place.
