Hmm. "Servers are pure RAM-based, no disks." And where whole system will be stored at? Random shutdown or reboot of server will cause in devastating of data. This isnt acceptable both for customers and girls. All personal data will be destroyed, and you have to do backups every hour or even more often with service growth.
OP you disappointing me, first when i've quickly read your tech papers on medium, I've thought "that seems flawless", but then i've read this about RAM storage, and about two TOR gates within your system.
Did you know, that TOR cannot provide an acceptable bandwidth for a service like yours? Especially when there is two tor gates in the network.
So, your security/storage plan is not flawless, moreover it's vulnerable and way too complicated in service.
And i've found strange thing. How it could be truth
that for 11 days of your ICO you've collected $400k and after creating bitcointalk thread you've stuck on 700 for days? Where was your main marketing campaign?
Differential backups every few minutes or less. Basically stream the database log to encrypted backup. This is not hard. It is not something we invented. It is a very common approach for RDBMS.
If the server is breached or otherwise fails (random failures are scary - why is it random?) then we have to restart and restore.
This is intentional. It provides the best security guarantees. Drop by our Slack and chat if you're not convinced. RDBMS data is small and restores quickly. Bigger data (photos) can be streamed from encrypted storage and does not delay restore.
Hosting via physical servers, not in Pink's name. This makes imaging them a very difficult task. Unlike VPSes which are easily imaged, including RAM.
Who claims things are flawless? I am not claiming our plan is flawless. I am saying it is vastly superior design and hard to improve without having a nation-state willing to back you legally. If you have particular criticisms, I want to hear them, please!
It is very common in ICOs to have a distribution heavily weighted to early and/or big players. Pink talked to people well before the domain was even registered. We have news articles in some huge mainstream tech and business sites coming out soon, plus some independent journalists. Sign up on

Tor will work fine. Aggressive prefetch and caching (encrypted to user access token) means few requests need to go all the way to the database. Plus we have some tricks up our sleeves to reduce latency. It is a challenge, but one we have figured out and feel very comfortable with.
