Anonymity of Ewallet sites

[deepdish]

Hello Everyone

What i was wondering about is the anonymity of the Ewallet sites.

I am registered to one Ewallet site that has a static deposit address in my account is it possible
to track down my account if the attacker knows my static BTC address or does the address
tell nothing about the website where it is stored? (assuming that the address is private within my account).
So for example the address could also just be a client running on a PC?


And on Mybitcoin.com if you receive a payment it says Payer: P2P bitcoin network is this for
anonymity reasons? and is the actual address stored on their servers?

Thank you very much! Just a few things im curious about and can't seem to find in Google.

If you're really worried about anonymity, you should be running the Bitcoin client on your computer alone.
