I recently created a Facebook group. I'd like to invite a bunch of people to join the group instead of adding them without their permission. Is this possible?
Just send them a Facebook mail with the link to the group and an explanation of why you think they might like to join the group.
Yes there is a way to add people in Facebook group with script instead of adding them one by one manually. This method bypasses limit of 1000 members so now you can add 1000 plus members in your Facebook group. https://hackingtryx.blogspot.com/2015/05/script-to-add-all-friends-in-group.html
