Thank you.
1. So why are people paying around $100 a year for the others?
Several possibilities:
1. They don't know about NetFree (NetFree does not advertise)
2. They do need something that NetFree does not open such as Facebook for example
2. Can you make a special request to open something they consider not Kosher?
I'm not sure.
I've heard that they do have a department that looks into such requests but I really don't have info about if it actually exists or how it works.
3. What about a typical website (i.e. Fox News) that may have pictures not for a Frum person - will it not open at all or do they block/blur the pictures?
The way they work is they review each website and if it is kosher (or can be koshered) then they open it for all the users. Additionally then have a staff of non-Jews in who check each picture in real time and if it is kosher then they open it for all the users. Otherwise they blur it.
Fox news specifically is blocked (as are most non-Jewish news sites) because they contain extremely problematic content such as celebrity news etc.
Fox business is open
4. Is there skin-tone covering?
No - images are blurred if then aren't kosher.
To date they've checked 886,991,350 pictures (according to their home page).
From my experience the review time for images is appx 15 seconds
Websites depend on the priority level which can be set. High priority is usually as fast as 5 minutes and you can see the estimated response times in your account.
In general I have the impression that it is an outstanding product but also that it won't work for some people because of specific needs.
