Is Black Book of Sex legit?

"Legit" usually means three things: a real company stands behind the site, it charges what it says it charges, and it's honest about what you're getting. Here's how Black Book of Sex measures up on each, as checked against the members area on 16 and 17 October 2026, plus the points we couldn't confirm.

Who runs Black Book of Sex?

Black Book of Sex is run by Ambervine Inc, a Delaware company at 131 Continental Drive, Suite 305, Newark, DE 19713, USA. The same name appears in the members-area footer, where accounts and payments are handled.

The domain was first registered on 4 November 2010, and by 2018 it was an Australian adult site; most of its visitors are now in the UK, followed by the US and Australia. You can check a domain's registration date yourself with ICANN Lookup, the public registration-data service run by the body that coordinates internet domain names. About Black Book of Sex has the background.

What's free and what you pay for

Joining, building a profile and browsing cost nothing. Reading and replying to messages need a paid membership, which also unlocks read receipts, seeing who has viewed you, likes and full-size photos. Free accounts see ads. Optional extras, such as boosts and an ID-verified badge, are sold separately.

The members area shows the exact price, currency and billing name before you pay, and the prices page explains the plans. Memberships, trials included, renew automatically until you cancel. That's normal across the industry, but it's the thing most likely to cause an unwelcome surprise. The US Federal Trade Commission's advice on trials and auto-renewals applies anywhere: find the cancellation terms before you sign up, and mark the deadline in your calendar.

What is checked, and what isn't

Photos are checked; people are not. In detail:

The members terms are candid on this point: they warn that profiles and interactions may not always be what they seem. That's true of every dating site, and it's better said than not. It means the sensible checks are yours: a video call before meeting, a public first date, and a firm no to any request for money. An ID badge tells you someone resembles their photo ID. It tells you nothing about their intentions.

The partner-site network

Black Book of Sex shares one member database with partner sites in the same network. Members of those sites can see and message you, and each profile shows the site its owner joined through. It isn't hidden, but it surprises people who expect a site to be a closed room, so it's worth knowing before you write your profile. How it works explains it fully.

What the members terms say

The members-area terms are the contract you accept when you join, and they're worth ten minutes before you pay. Points to know in advance:

• they are governed by the law of Delaware, USA;
• disputes go to arbitration rather than court, and there is a class-action waiver;
• refunds are covered there, so read that section before you buy, not after;
• the members-area privacy policy explains how your profile and account data are handled, including the sharing with partner sites.

If you live in the UK or Australia, you may still have consumer protections under your own country's law that a contract can't remove.

What we couldn't confirm

Being straight about the gaps is part of the answer. As of 17 October 2026:

• Currency. The plans we've seen are priced in US dollars. We haven't confirmed whether UK or Australian members are offered pounds or Australian dollars. The checkout shows the currency before you pay.
• The exact statement line. The billing name shown at checkout is the one to rely on; we don't print one here because we couldn't confirm which appears on every card statement.
• Response times. The site publishes none, and nobody is obliged to reply.

A five-point check before you pay

Use this on Black Book of Sex, or on any dating site you're weighing up:

1. Find the company. A named operator and address in the footer and terms, and the same name in both places.
2. Read the free-versus-paid line. You should be able to tell exactly what a membership adds before you buy it.
3. Find the renewal and cancel route. Here it's Settings > Billing, and deleting is avatar > Settings > Delete Account.
4. Look at the checkout. Price, currency, plan length and billing name, all before you enter a card.
5. Read the terms on refunds and disputes. Two minutes now saves an argument later.

Who it suits, and who it doesn't

Being legitimate isn't the same as being right for you. Black Book of Sex is a reasonable fit if you're an adult who wants something casual, is content to look around free before paying, and doesn't mind a profile being seen across partner sites.

It's a poor fit if you want every member's identity checked before you talk, a closed site where only its own members can see you, or a promise of replies. None of those is on offer here, and a site that offered all three would deserve a second look of its own.

How to tell if a particular profile isn't genuine

Any dating site, however it's run, can attract the occasional fraudster. The warning signs repeat:

• they ask for money, gift cards or crypto, for any reason;
• they push you to "verify" yourself on another website that wants card details;
• they want you off the members area and onto another app within minutes;
• they press for intimate photos before you've met;
• they always have a reason not to video call.

Report them through the members help centre with their username and screenshots. If you've lost money, call your bank, then Report Fraud in England, Wales and Northern Ireland. Staying safe lists the routes for Scotland, the US and Australia.

The short verdict

Yes: a real company runs it, the free and paid parts are clearly divided, and the network sharing and lack of profile checks are stated rather than buried. Go in knowing that plans renew, that what members say about themselves is unverified, and that discretion is your job as much as the site's.
