It will also be important to add the rules of that competition or any other competition that is reference too. Some organizers state that you must have registered xxx number of months before the announcement was made. If one is allowed to register and smoky join the contest, they are not breaking the competition rules or forum rules. If the contest does not allow alt participation, there is a hint they are breaking that, but we'll also need to know if their alt is enrolled too.

Overall suspicious behavior, but can be quelled by some details being added to the rules of the competition.
