There is no campaign yet …
I am just setting up an opt in to assign a btg tag to those that sign up for the Bridge the Gap newsletter with a tracking tag on the confirmation page when they click on the link in the confirm email address.
This is the string I use on confirmation page where members opts-in their email address

Here the segment setting I set up to add those contact with the tags into the segment.
But it still adding blank contact with ip address when the confirmation page is hit by someone without a link from email or from a bots.
Here a screenshot log when I go visit the page confirmation page. without a link from email. (my ip address edited out)
It seem it will create a new contact just by visiting the page with blank email and name. I could be wrong
It does not appear in the contact list and. remain invisible however it does appear under the segment’s contact counts and contact list.
Only 3 shown in contact list - those are for testing purpose …It not on live production yet that why it only have 3 contacts.
There are total of 11 contacts in the segment with btg tag … 8 of them have ip address only and it is hidden but it annoying to see it being counted when there is 3 with email and name attached to it while 8 are blank with ip address only.
I can only guess it being created whenever a bot or someone discovered the page without the confirmation link.
I could be wrong about all this.
