This is a legitimate concern. Our internal conversations on Discord solved this problem months ago. Essentially there are a number of ghost accounts setup to make challenges and match reporting daily so the test competition admin will have interaction on their ladder and actually be able test all the functions of the solo ladders.
I like the idea of having an actual official test competition or actual “GWL Official” game competition for members to join. We’ll make that part of the discussion/agenda this weekend for our weekly GWL Staff meeting. I’ve actually had a couple people from the “Combat Arms” community reach out to me on Discord. So far Combat Arms has been the only community to reach out so that may be the place to start.
