I don't think having separate accounts will help, since they'd all be linked to your real name, and your real name would be displayed to other members of AVOS-Delicious.

I think I might use the contact address to lodge a complaint -- I understand why the company might want my real name, but I do not understand why they think displaying it to all other members is a good or desirable thing.

If I can't restrict my info to keeping my real name private, I don't really want to use that service. The horrible privacy issues are what keeps me off Facebook, after all.
