Though one should not trust in that a website or wallet is checking if the address one is sending too is valid. There are, most probably, websites that does not check if the bitcoin address is a valid one. Sending the coins into nirwana.
Though when i think about it. Maybe miners would not implement such transaction in a block then. Or no, it would be too time consuming for them to test if every address in the transactions are valid.
