We don't want to argue with anybody but try to behave like normal people with normal questions, we are opened for your questions and explain things until you start behaving aggressive
Before starting a business, you should learn to be professional. I have told you that you have few spelling mistakes in the website, there are still few mistakes I can see.
You could provide a signed message from an address which have the balance of maximum amount allowed for mixing in your website. In this way, you could increase the trustworthiness. You are not the first mixer who denied to sign a message, you are not the first mixer which have been asked to sign a message. I have seen other mixing threads where community asked for signed message and they provide signed message. This mixer still exists for years and have no bad reputation.
You didn’t follow anything, nor you have behaved professionally with forum user.
I don't think your mixer is a good one, nor would I recommend to anyone to use this.
