Unfortunately, TT does not have a mechanism for Pros to rate or otherwise comment on job posters. If that functionality were available, it would allow you to flag that problem to other pros she may try to contact. It would also give us Pros a way to weed out habitual tire-kickers.
@STP-ZFC thank you for bringing this to our attention. Thumbtack has high standards for pro and customer safety. Anytime you come across a customer or situation you’re not sure about, let us know by reporting it. You can find the steps to do so in this linked article: Report Suspicious Activity.
You can also reach out to our Customer Support team by clicking here to see the option to contact Customer Support (found under the " Need a different way to contact us?" section).
