What he did is that its a particular part in al-kharid that is realy BIG to load and this is a know strategy to target people who have said lag etc and drag them to border then when your loading its to big and your pc is to shitty or your internet is shitty so you lag and freeze.
Sadly to say the easiest way to get this over with is roundhouse kick ass him, and i mean it, by this you humiliate him and he will never contact you anymore + you will get respect from others
