The following user was in the PHP room (had also visited before many times). When I clicked on the user profile on stackoverflow.com link, it redirected me to a 404 page. But the user exists if searched from the users tab on Stack Overflow:
- https://stackoverflow.com/users/686733/jamshid-hashimi - 404
- https://stackoverflow.com/users/461181/jamshid-hashimi - Real Profile
Is this a result of profile merging? If yes, than why there are 2 different links for the same user?
