As for memorable trolls, I remember the one fleeing from abroad as well, she was in Japan IIRC and posters came together to get her a house, money, clothes for her kids, it played out over a couple of weeks, And if I remember rightly it was the poster’s own mother who outed her to one of the posters who was on board with helping.
There was a troll (and for the life of me I can’t remember her name) who was going through a divorce, then found out she was pregnant with twins, communicating regularly with other mums who had lost a baby, then she sent a message to another poster saying that she was rushed to hospital with a bleed, and then that she’d lost the babies. Came back posting in the night completely incoherent compared to how she wrote before, and saying that she was broken and didn’t want to live. People were offering help money, emotional support, some of the posters who had had stillborns offered her their time and their help. The threads went on for pages and pages and over the course of a few days. but she’d spent weeks building her persona.
Then someone started another thread saying that although she knew she might be flamed she felt she should warn people that they can’t always be sure that someone is who they say they are and for posters to be careful. Because the site was much smaller then everyone knew who she was referring to, and while some came on to give support, a lot of others said they’d been suspicious. The threads were taken down, and then the poster started claiming through others that she’d been told to provide all her personal details as proof she wasn’t a troll.
She kept in touch with a couple of posters, and then it turned out she’d trolled over on one of the baby loss forums, complete with pictures of her dead babies which turned out had been lifted from the internet when another post searched them. So she was officially confirmed as a troll then.
