I have own domain and use unique address and password for each service. This lets me know which one leaked it. When Adobe lost both my address and password I tried contacting their support (I was paying customer). The support person repeatedly said they checked and my credentials were safe. This regardless the fact I had proof. Very disappointing. Since then I had couple other situations like that. I guess companies assume users are idiots and use same password everywhere and so they feel safe nobody can prove it is them ho lost it.
