How long does it take for someone to be banned?

So recently, I had an RS trinket ninja-ed from me and I promptly created a report with a pretty solid evidence trail starting from the raid leader's recruitment post on global chat to the MS changes, and all the way down to the rolls and who the raid leader said won (which directly contradicted the rolls and his own recruitment terms).

I felt like I've already included everything for a rock solid case but the reply from Warmane is the usual, "The player(s) mentioned will be investigated." and no follow-up after.

Meanwhile, I've seen the perpetrator online and going on about his day, clearly not having been banned.

So I guess my question is: does anyone know how long it usually takes for Warmane to come up with a verdict on cases like this or is it safe to say that by this time (2 weeks after report was submitted), the case has been dismissed and the perpetrator has been deemed not guilty?

Usually they first ban if that would be the case and then reply with "the player has been taken care of" or something like that. From my own experience every time I've received such reply - "The player(s) mentioned will be investigated." - the player wasn't banned. One such case was when the leader stole all of the black temple boss' loot and just hearthstone in front of us. LOL. I guess it's just easier to reply like this instead exceeding with information you don't need and they're not obligated to provide to you.

I suspected as much too man. Thing is, I've done reports in the past which I didn't put too much effort in and have gotten the "This player has been dealt with" reply.

This time, I really wanted to make a solid case with screenshots of every step of the raid from recruitment to roll and al I got was this cryptic answer instead. Really makes you wonder how people are picked to be banned.

Idk about ninjas but I've had multiple GM auto-responses from reporting bots, and they get banned like 6 hours later
