Briefly adding my two cents to this thread. I don't get stuck in endless Captchas, because as soon as they appear, I just leave. EBay has lost several sales this way. I do have a mobile web browser that operates through a proxy in the Netherlands (I'm in Pennsylvania), which could be a red flag, but it also happens sometimes on my desktop computer, where I don't save cookies. If I was doing something ominous, I could understand, but these regular false positives are hurting your business. They almost seem random...or perhaps become obnoxious when EBay thinks it's experiencing a security issue? If anybody from EBay support wants to contact me privately, I can reply when the next one appears. Would love to know what's really triggering them.
