Did you ever get a satisfactory response to your question? I am going through the same thing, and even got locked out of my account for two weeks because two legitimate reviews were posted, then flagged as fraud within the same week! As a full time free lancer that is the ultimate low blow. On top of that, there seems to be no recourse. Not even a formal "report a bug" feature. The only Dispute Resolution service they offer on the website is for Customers, Not Pros. It seems odd, because last time I checked, we the Pro's ARE the paying customers on Thumbtack!
I have done a live chat, two phonecalls, and no one in the support staff is allowed to connect me with the Trust & Safety Team. In return, I've recieved several template emails. I'm stuck waiting to be contacted by a member of Trust & Safety...its been over 4 days!
@jandersonica I'm sorry to hear that this has been a point of frustration for you. At this time, the best course of action will be to wait and discuss with our Marketplace Trust & Safety team as you've mentioned, and they will get to you as soon as they can. We appreciate your ongoing patience with this.
