All the small chans got these. It goes on for years now (well over 5 years for sure). Frequency varies, sometimes couple of times a day, sometimes it skips weeks. Noone has any idea who does it or why, or how can they do it still.
Delete browser cache when happens. We try to remove ASAP, sometimes can catch it right away, but sometimes can sit on the site for some hours.
We ask board staff too, BOs and BVs to delete them.
