| The best and easiest way to check who's blocked you is to open your msn, click on your name at the top, go to personal settings, then privacy. Then right click the contact in the allow list, and if they've blocked you, the delete option will be available. If they didn't block you, the delete option won't be available for them. This is the best way of doing a check on all your contacts to see who's blocked you. |
