The friend request limit is almost useless and will barely do anything. "Blacklist and report" option has been needed forever and is still needed. Anyone who receives several reports should be squelched (unable to use say/shout/tells and can only use guild/linkshell/tells to people who have friended them) until their case is reviewed. Anyone who abuses the report feature should no longer be able to report.

No idea why FFXIV won't make a real fix for RMT and keeps doing useless stuff and ignoring suggestions that will fix the problem.
