There is surely a problem with Sky news (who are steadfastly ignoring this at the moment, when if any other channel had been involved, it would be exactly the kind of lead story they cover) acting as judge and jury. No matter what you think internet trolls deserve, surely you think they should get that after police investigation/trial/mental health assessment. Someone could kill themselves after being mistakenly identified as a troll if the media can do this.
If you don't like people being targeted and abused without accurate knowledge or compassion, then I'd have thought you'd have hated both what this woman posted, and what was done to her. Just an initial reaction though. I don't have personal feelings towards her, but I do have worries about the way this was handled. If that becomes the norm then all kinds of innocent and vulnerable people could be hurt. I don't think bullying the bully is always the best way.
