Yes, I understand that. I viewed the thread as casportpony, logged out and logged in and both posted as both majormagic and peadawg, which should have sent 1 alert to casportpony, but it did not.
Try going here:

Select both of those & save, then de-select them and save again.
After doing this most of my alerts disappear after I click on the bell icon.
