I've checked the numbers of our confirmed users and, unfortunately, many of the accounts never confirmed their email address (this could be due to a bug in the confirmation process or simply due to spam).
I decided to update the stats on our homepage to only include confirmed members, in order to give us a more realistic sense of progress and know how many people actually share our values and commitment. I believe the current number is more in line with the activity we saw in the forum.
This is only a metric, as it's impossible to know for sure what the intention of each user was when they joined us and it's also not our goal to control our citizens. If they prefer to remain anonymous, that is still perfectly in line with our values.
If you're one of this citizens who never confirmed their email address, you're still welcome to do so at any time and, once confirmed, your registration will be anonymously counted towards our progress goals.
