This might be related to buddypress!!
Imported users are not listed nor searchable on members page in buddypress.

Maybe expected behavior as with no roles for imported users?

As far as I'm concerned, this is a BuddyPress feature instead of bbPress bug. To avoid spam, users have to activate their accounts, instead of being imported.

This is expected behavior in BuddyPress, largely to avoid spammy users who have never logged in from appearing in the members list.

Users aren't "Active" until they've logged in, at which point they'll get an entry in the bp_activity database table to expose their last activity time. Until that happens, they will not appear in the members directory under "Active Users".
