Find Minecraft Names?

Jmd once told me that there's a website where you can see what the Minecraft account was last. I would like to change my Minecraft name, but it is already occupied and wants to find out if I can't buy it. It is the MC account: "Basti"

https://de.namemc.com/

On namemc one does not see, however, where the account was last

Do you mean on which server? There's no such page.

But apparently

Certainly not. First, there are too many servers and secondly, privacy would be useless. There are servers that use certain plugins which allow players to identify themselves on other servers with the same plugins. But there's no general list.

How can I contact the person?

Well not if you do not accidentally meet her somewhere. This is not intended to contact accounts. Data protection technology would also be a disaster.
