There is a simple reason for this. We get a lot of phishing, spamming, and other objectionable requests for personal information because we openly advertise contact information for authors who wish to contact us through the submission process. Unfortunately we also get a lot of submission contacts from people with an agenda other than getting their writing published. For instance, we've had people ask for an advance before the contract is even a consideration, simply because they are looking for money. And when we refuse to skype or talk on the phone about it, we receive threatening and psychotic responses. There are unfortunately a lot of people out there who live in a different reality, which makes ours difficult to deal with. If you look at any publisher site you will not find personal phone numbers and addresses of editors or other staff. Nobody gives out that kind of personal information ... for the same reasons listed above, to avoid needless harassment.
