We have noticed that anybody who registers for our TeamRaiser event is receiving this achievement badge on their personal page. Shouldn't this badge only be assigned when someone makes a donation to themselves?
If you have enabled the option to include registration fees to increment towards fundraising goals, then any constituent who registers for the event will receive this badge. This is because the system considers the registration fee a "gift" and counts it towards the participant's fundraising progress. As such, the personal page is immediately attributed with the badge.
