Hi gang,
We'd love to tell you that there was a definitive way to spot a troll from your side of the technological fence, but there isn't, not really. We see the reports, and a lot of the time we can see that people posting The Most Outlandish Tales are long term posters on a name change and in fact everything they're saying chimes with previous posts under other names.
So, you might see people saying 'we knew all along' when a troll is revealed, but only HQ can see the eleventy million times they've reported people who actually turn out to be their bessie mates in disguise.
We hope that we at MNHQ strike the right balance between benefit of doubt and righteous fury when threads start to get a bit whiffy - we're beavering away here in the background trying to make stories stand up or fall down, but we are utterly reliant on you all not publicly troll-hunting to do so. And, sadly, we would ask you all to not give more, whether that be emotional support, practical or financial, than you can yourselves afford.
So, we guess what we're saying is... no signals, no... it doesn't work. Not even Cheshire scumbag.
