Hi Annandael,
We do not think that a phone number/first name can cause identity theft as phone numbers are publicly available information.
We are not asking sellers to provide their social security or credit information in the for sale post. Those things can cause ID theft for sure.
If the post is made by a legitimate breeder who has nothing to hide, we do not see why he/she would have a problem posting their phone number.
Most of the breeder websites that we looked at had a phone number listed on there, so potential buyers feel more comfortable and can talk to a real person.
We will look into this some more and maybe either hide the contact info in the post for unregestered users or make an exception to the rule.
Thank you for bringing this up.
