BYP WIKI requires no personal information from anyone who wishes to edit it. The IP addresses of editors are logged, but only visible if the editor has not created an account name. Some editors use their real name for their account, most others use a pseudonym.
There are some reasons why it might not be a good idea to list your last name, street address and/or phone number on any wikipage (or indeed, anywhere else on the internet). The main reason is that this information is freely accessible to just about everyone.
Although it is your own responsibility, you are advised not to list personal details such as contact information here. We recognise that those who are advertising will wish to list some contact details and that is done at your own risk.
If you have any concerns related to your privacy, contact an administrator for assistance.
