As you know, the tournament listings have been a complete mess for a long time. I would guess that 95% of the listed events no longer exist. My proposal is to mark as cancelled effective Dec 31, 2018 every event that has not been updated by one of our users in the last six months. This would be done manually, by me and anyone else who wants to chip in. (We would want to work at different times to avoid collisions in effort.) That would at least prevent most of the false positives. Thoughts?
