Hi, Snoopy, welcome to the forum. The guidelines of our forum prohibit revealing the client names of mystery shopping companies, which is why the moderators edit posts which reveal the names of clients. By posting on the forum, we all agree to follow the forum's guidelines, thus, regardless of whether a company has a confidentiality agreement in their ICA, our guidelines determine that we do not reveal.
When a shopper registers with a mystery shopping company, he is required to sign an Independent Contractor Agreement (ICA). About 80% of these ICAs contain confidentiality agreements. Some of the confidentiality agreements are stricter than others, but almost all of them prohibit the mystery shopper from revealing the company's clients and "proprietary information," which is sometimes not clearly spelled out by the agreement. By signing the ICA, we enter into a legal agreement with a company, and many of us are very serious about that agreement.
When a poster violates an ICA by revealing a name or information that appears proprietary, it is usually because the poster is new and did not know or understand OR because he simply slipped up. In both of those cases, other posters frequently "warn" the poster, and many times the poster edits his own post before the moderators do. I would say that most forum members warn each other because we "watch each other's backs" and we know that in most cases the poster would not have intentionally wanted to dishonor their agreement with a mystery shopping company.
Another consideration is that this is an open internet forum and it is available to anyone who has access to a computer. Although we are primarily mystery shoppers, many editors, schedulers, mystery shopping company administrators and owners also read here. There have been times when a poster compromised an ICA and was contacted by the mystery shopping company. There have been other times when a poster posted a story about a company only to have the company post their version of the same story. It sometimes makes for interesting reading.
As for someone else's ICA violation affecting you personally, probably not. And, as to "What would be the consequence of ICAs NOT prohibiting shoppers from freely sharing this kind of information? What is it that the mystery shopping companies are so afraid of that they feel like they need to make this, seemingly, a standard part of all ICAs that all shoppers must agree to? " That would be a question for you to ask each mystery shopping company. When registering with each company, you can read the ICA and determine if you are willing to agree to it or not. If you have questions about a particular ICA, you might ask questions of the company before agreeing.
