I can kind of understand them wanting to put some hurdles and hoops to the whole reporting business. It discourages false reports, or reporting every single player who doesn't talk back to a stranger's greetings all the time XD They'd probably be quickly overwhelmed if it was fast and easy to report everyone.

I do think that works against them too though, as a lot of people will be similarly discouraged from filing real reports and getting rid of some of those gil sellers...
