The state of ADULT content tags these days? (parental filtering)

[Allfetish]

Years and years ago I looked into registering my sites with some of the content filtering organizatons. However I was dismayed that they wanted all this personal information from me. Thus I opted not to bother. I'm only willing to give out the site and an email address or two to reach me. I don't feel as if I should have to provide my phone number, Full name, physical address, etc. I think that is ridiculous. All I'm trying to do is do my part to help keep kids out.

How is it these days? What tags or organizations can I register with whom are not overly intrusive as per the above.

What do you use? Is this still needed these days?
