It's a minefield.
It is possible to clamp the whole section down, such as it would be far smaller and far more secure.
It's also possible to close the section down completely, safer still.
At present, it is policy to leave as is and try to be reactive to the scumbags who happily accept other members' passwords thoughtlessly offered, and those new members with those damn links in their PMs.
In a word, minefield.
