As others have said, this is an adult site, but apart from that it's about as trustworthy as you can get - it doesn't even have pop-up ads! Please note that it's the new version of asian-sirens.com, which has a well established reputation for trustworthiness.
This is an adult website, and by definition is not suitable for children.
I have had no indications of spam, or anything else which would render it untrustworthy.
If you don't like the content, don't visit the site. Don't however inflict your biased views on other adult readers.
