[NSFW] /wp-admin/admin-ajax.php ? | WordPress.org

Hello,

in my backend logging constantly appears this entry
	/wp-admin/admin-ajax.php and that people try to access it from the backend.
I have locked my site for various country zones, the backend can only be accessed from my home country.
Can anyone tell me why this /wp-admin/admin-ajax.php entry keeps showing up in the backend logging?
