So I wrote a script that auto-expires the bans in ip.can and ip-silent.can
it is called banTool and you pass it the days for the ban to last and the file(full path) and it will scan it and throw some comments in the file for "book keeping". I have it set to run at 00:01 each day and I have seen no problems yet.
(I would just check out to make sure that the permanent ban line is up near
the top of the file after the first run)
It runs fine as both a native event or with slightly fancier display from jsexec


Do you see any tweaks or anything wrong with it?
