Yeah, I remember the diss command on Firan being a complete shitshow -- basically, as soon as someone with enough OOC popularity decided they didn't like someone, no matter how slight the IC reason, it was dogpile city. It was also often used as an OOC means of attack: I don't like you, the player, so I will keep an eye out for even the smallest IC infraction and then grind you into social nothingness ICly.
It doesn't surprise me at all that the same type of behavior reared its head on condemn.
If you ever consider bringing it back, perhaps instead of having a direct effect -- all these condemns = immediate social loss -- there can just be a threshold that needs to be attained. If someone reaches X amount of condemns, it gets put on staff radar. And then they can make the call whether or not it's worth a prestige adjustment.
Granted, it puts more work on staff so .. probably nah.
Anyway, sidetrack done. As far as anonymous messages go, when I first started playing, there were a few times I wanted such a command -- mostly to send people secret presents and stuff. But I adjusted pretty quickly to not having that functionality and I can't say I miss it. The potential for abuse is high and if you really want to get up to some hijinx, you can just do an action.
