Flag members mod?

[Jon_Simmonds]

Just wondering if there is any mod out there that lets a mod flag a member for what ever reason, and that flag is just visible to mods/admins etc (similar to the flag system in outlook)

e.g a new member signs up who you suspect is a troll a mod asigns a flag then while other mods are browsing the threads, they see a "troll flag" and can double check the post/thread

While infractions etc can be used, in some cases it makes for a "harsh" environment and in some cases its better to sit back and watch
