Well, I am not sure how a lot of other sites work, but with my site, you provide an email and password of your own, click one little box, and every time you visit the site, it remembers your login and you get right in automatically. Hey, and if you don't like what you see, you can always click a single box to "unregister"..... Regarding spam, we only send out one message a month or so about any sales.
As for searching for niches, Our content is organized in over 50 different niches, so you can click on just the kinds of content you want. On my site you can see a thumbnail of every image you purchase, and you can pic the images you want as well.
I would think content customers (webmasters) wouldn't want every tom, dick, and harry surfer cruising around in content sales sites getting for free what a webmaster wants to charge members or other customers a fee to see in the first place.
I know content is just a part of what a successful webmaster needs to make money, but like any part of a business, it's important enough to get the best quality and value you can out of your dollars, right?
Isn't that worth spending a little time and effort on?
Tom
