just like you said, it's a failed idea before it could even start or it's already failed!
you should already have an answer before you even started this thread.
When I started this thread, the situation differed from today's situation.
Back then, the situation boiled down to the responsible people just being silent about their product and why I couldn't access my portfolio.
Now, what crystallizes is that they seem to have deliberately designed in a manner so centralized that they could just relaunch it, thereby flushing early adopters' portfolios.
This leads me to the conclusion that the architecture may not be viable enough for me to recommend this system to fellow keyword marketers or search engine enthusiasts.
However, I do not regard the idea as a failure, which is why I'm now working on a more decentralized architecture. Again, interested people are invited to PM me for getting involved in the early design discussions. Maybe the efforts can even be merged at some point, getting the best out of the efforts towards decentralization and robustness together with the results of the already exercised marketing efforts.
