These are part of the "post before register" feature. That email is sent out when a user has posted, but not subsequently entered valid registration details. The only way in which you would be able to stop those completely, would be to switch of post before register. You can see more about this here
 
 

The last few weeks I have started to get email from my IPB, see below. These are obviously spammers that don't have a legit email address.
Is there any way to NOT get these emails?

Okay after a bit more digging into the code, i see why this can happen.
it is any theme hook, that has an override for a template in it or aka "theme hook in php mode"
try{ if ( eval( "namespace IPS\\Theme;\n\n" . str_replace( array( ' extends _HOOK_CLASS_', 'parent::hookData()' ), array( '_tmp', 'array()' ), file_get_contents( $path . '/' . $data['file'] ) ) ) !== FALSE ) { $class = "IPS\\Theme\\" . $data['class'] . "_tmp"; $templateHooks = array_merge_recursive( $templateHooks, $class::hookData() ); } } catch ( \ParseError $e ) { } in php 8.0 it is now a fatal error to call a non existing parent class/method, in the latest php 7.4 it is a deprecated.
so since at this point, the hook in php mode isn't actually extending another class, it is blowing up. this is def an engineering issue on IPS side of things. so technically any theme hook in php mode, that eval and try to call a parent method that doesn't exist, will throw this fatal/warning in the current versions of php. we don't see it while IN_DEV cause templates are compiled differently there. 
i wonder now if it happens with class hooks, that get wrapped up by IPS try/catch block they place inside every method, even if the method doesn't exist in the parent.  
 

Not that this helps anyone, but I've scrapped all login handles now. Sick to death of all the changes and how difficult it is to keep them running. IPS registrations only now, giving us full control over everything. I truly think it's the way to go now. I've even removed all the promoted article social parts and just push the posts to our home page.
I cannot wait for FB, etc to just die. Die already will you!

In the Facebook login settings it says:
Normally, it shouldn’t ask for an address. I don’t know under which conditions the email is not delivered by Facebook. Maybe it’s a privacy setting for the user? Or a misconfigured app?
