Hi, here's a conclusive answer to the OP's question:
Flipping.co, domaining.com and valuate.com are all under the same ownership and you can use them all with the same domaining.com account.
Estibot.com is independently owned. We do not share account data OR appraisal or user search data with anyone because we are fanatical about privacy. The above mentioned sites use Estibot technology in the back end by a licensing agreement. Data goes only one way, from estibot to the other sites, via API. Estibot.com does not share account data with any of the above services, and the domaining.com network of sites does not share account data with Estibot.
To summarize:
1. Estibot.com does not share account data, account usage history or any other individualized data with anyone.
2. Domaining.com, flipping.co, valuate.com and bargaindomains.com are all part of the same network (of which Estibot.com is NOT a part), and whatever data they share with anyone can only be answered by Francois the owner, who, as far as I know, runs a very transparent business and I'm sure would be happy to answer any of your questions in detail.
Having thus officially separated us from the domaining.com network of sites, I emphasize that we are very happy to collaborate closely with Francois of domaining.com with whom we continue to work together to build better services for domainers.
I hope that answers the questions presented here
Thanks
