When you're looking at an adult website, you want to know who's behind it and how to reach them if something goes wrong. primio.lt does have an about page and a legal entity disclosure listing business details, which is a positive sign. Most legitimate adult sites also make it easy to contact support from the homepage — primio.lt doesn't, and that's a noticeable gap.
The domain has been around for about a year based on archive records, and it's clean on malware blacklists. The security setup is decent but not cutting-edge: the SSL certificate is valid, but the server still accepts older, insecure encryption protocols. Combined with the missing contact info, it's wise to be cautious. If you decide to browse, avoid sharing personal details until you're more confident in the operator's transparency.
