End of Story

Domain expired and this time I decided to close the service. Notified a handful of active customers and shut down the server. During these years the project generated some revenue but never got any real traction.
I suspect that the issue was initial bad naming. Deep Web was totally confuser with Dark Web, the website was penalized by Google and maybe it was all different If I chose different name. But I don't have interest in the project any more to give it a second try.
Starting another journey. Stay tuned.
