So it does have a slight delay.
I'm having an issue now where the option to Report a gil spammer isn't on the list when I click on the name. The only options I have in the list are "Send Tell", "Invite to Party", "Send Friend Request", "Add to Blacklist", and "Target". Even if there's a maximum number of reports in a certain time period, it's been at least a day since that option has shown up for me.
