We don't take screenshots because they are incredibly easy to edit, and logs can be forged too.
/report is meant to log the 5 minutes of the target's chat, and that's all it did. Kind of. There were some problems with its system

GMs don't get a notification, but we do have a place to check all reports, and it's checked daily. If you have a problem though, it'd be easier to first see if a GM is already online (
/who game) and notify him or her to get the problem taken care of quicker.
However, the command will get a makeover to make it work retroactively - meaning that once it is activated, a chatlog of the previous five minutes will be stored along with the next five, to make sure no misbehavior escapes the consequences.
