The Association of Independent Businesses is a free to join open business community. Members can make use of various features but so can the public. The AIB allows you to publish feedback about a member and their online business. This way potential customers can make an informed decision.

One of the services they offer to members is help and advice on how to secure their websites and make the whole customer experience safe and enjoyable. So if you find that is not the case they will publish your report and take that member to task. Reputation is everything to online traders and they don't want to dent that in any way. You can visit the AIB at The Association of Independent Businesses  for more information. You can also follow them on Twitter at Independent Business
