/*
|
|
prune IPs from old posts (actually, rehash them with a temporary random salt to maintain
|
|
post history and prevent *-by-ip action unintentionally deleting many posts)
|
|
NOTE: ips may still remain in the following collections:
|
|
- bans, because bans need the IP to function
|
|
- modlog actioner ips, modlogs are already auto-pruned
|
|
- ratelimits, these only last 1 minute
|
|
- stats, these last max of 24 hours
