@trademark or maybe because wasserman is in charge of the marketing/communication in the project. Even if frank wrote in the thread would not be enough for some users because they do not believe it's him as it did before. I have to search, but in the past he wrote a statement here with his user.
That's why they need to confirm their identities with Sebastian before he releases any funds. If they do not exist, the project is a scam and will not be completed.
