This site contains all manner of X-rated (pornographic) material. I have no reports, but usually "free" porn is a scam and can install PUPs and viruses onto your computer. Stay well away.
Opens a persistent popup where you must click to leave the page, and clicking is agreeing to whatever they happen to want to do to your computer of info. Not just naughty content, naughty programmers.
This is indeed an adult related website, but for everyone commenting about malicious content, viruses, or malware infections, you should dig deeper before stating things of this nature. I scanned this website with 3 different services, and each one came up clean. This website has NO Malware, NO Viruses, and NO Malicious Code/Content.
You can check the results yourself.
