Going back to your question:
[...]
as we can see this user send all altcoins to this one address 0x2159d6ab53588fc4a8cc9e8eac33764038343f40
[...]
If all of them sent the payments to one address that's enough proof to link these accounts together.
Although, I have looked at there addresses and I don't see the addresses sending $$ to the main one. Are you sure you posted the correct address?
