After multiple inquiries as to the necessity to Sign In on RRS.org in order to file a protest, I have removed that restriction. And because of the limitations of Captcha and/or a keyword approval process, they are not implemented on the form. Thus, when a competitor clicks on the File a Protest link, they will no longer be taken to the Sign In page if they are not signed in. Instead, they will be able to submit a protest on your event without any authentication. However, the link is only active while an Event is listed as Active (see the Event Edit page). Thus, the link to your event should be available for only a limited period of time if after your event you change it to Archive. Hopefully the bots won't find the protest form for your event in that short period of time.
I would appreciate feedback from your experience with this change. If you find you are getting protests submitted that are either spam or fake, please let me know. Hopefully this will be a moving target for the bots and we won't have a problem...
By the way, if you have questions about how to use the Event Panel, there is some information here
