Hi Scott,

Staff will be making such decisions under intense scrutiny. Any
judgment they're forced to exercise will tend to be the most lenient
the policy allows. Which is to say: no restriction on repeat requests
at all.

Giving staff discretion can be a good thing if done with appropriate
checks, but you also have to give them a policy vehicle that validates
and reinforces that discretion. In other words, it's better to say,
"You can have 1 a day but staff can waive the requirement" than "you
can have as many as you want but staff can limit you to 1 a day."

Most likely he'll take the /18 and then go find a bunch of /24's on
the transfer market. Which defeats the purpose both of having a
waiting list and of trying to build to aggregation. That's why it
concerns me.
