So, it seems that if you create a forum account, it also creates a Ore account. Does it create others as well? Sorry if this is a silly question.
It’s just one account, but you use that one account for all things Sponge (it’s “single sign on”). So, it acts as your login for the forums and for Ore. As I guess this is linked to your deletion request, deleting your forums account is the same as deleting your Ore account.
For what it’s worth, for anyone who stumbles across this in the future, your account can be managed at https://auth.spongepowered.org/ (note that you cannot self delete though it - the right way to do it is to put a request in the meta category on this forums, our admins will handle the rest.)
