If you have received unsolicited email (spam) from an email address at bento.com, please do not report it to us. Spoofing of email return addresses is a very common practice of spammers. It's very easy to send mail from any made-up address, and there's obviously nothing we can do about it.
Bento.com does not send unsolicited email, and we do not allow our mail servers to be used by spammers.
If you wish to complain to the people who sent you spam, obviously they would be the people whose website is advertised in the spam.
