It seemed to work, but the thing is that people are still able to connect more times than I actually added. I added a host like so: /os exception add +0 *.example.com 1 <reason> (putting a reason of course).
Also, anope said something about being able to configure the notice users get when they are killed after said number of allowed connections? How would you configure that. Also, too, operserv said something about params, it doesn't list them unless you count: list, view, move <num> <position> as a param.
