Don't waste your time. They will go back and forward with you, asking for information that's already elsewhere in the survey and will have different people continually pester you for more information, instead of having them communicate properly and ask you as a single message/note. Question wordings are too vague and then they'll accuse you of not including enough information in your answers. Survey briefs are basically designed to have you outed as a mystery shopper (i.e. asking for store INTERIOR photos, which would inevitably flag suspicions of store employees - or asking you to describe an item as something it's obviously not). Payout is tiny compared to the hassle of having to continually go back to the surveys. Would be worth it if they didn't mess you around so much.
