We are reporting scripters, ninja looters, racists etc.
However, we aren't able to know if they are banned or not, I am just adding them(can't see the last login time) as friend or checking if they got any new achievements on the website.
I suggest a feedback system in in-game tickets like, "The report you sent is investigated and the player is banned".
No such feedback is provided on purpose.
That's a standard for this type of thing. Plenty of multiplayer games even have a message informing that nothing of the sort will be given when a report is sent, like FF14 and Lost Ark.
