We were asked to stop this for regulatory reasons. This could be construed as scheme/league/competition, which isn’t allowed by regulators. Is it really that is debatable, but if we are asked to stop, we have to. We never advertised this for the last 3 years, so the participation was limited to only people who knew about it - less than 10% of our clients.
I will probably share a post on zconnect on all major trends we could spot with 60 day challenge participants.
