Hi there,
My moodle 2.5.1 site has e-mail enrollment, and in the last year or so I've found an increasing number of people from other countries enrolling. They can't get in, since I have enrollment keys for all my courses, but its becoming annoying.
Could somebody tell me who these outsiders are, and why they would bother to attempt to enroll in my courses? Are they generated by bots or something? To me it seems a complete waste of time and resources...
More importantly, how can I prevent this from happening? It's not serious but it is bugging me.
Many thanks for taking your time to answer these questions - I do search, but only rarely do I seem to find effective keywords for finding the answers I want.
