I remember that there were multiple cases in which one forumer pretended to be someone else on a different account. As Hiraeth has mentioned before, one year on WoF, there was a person called Dragonfly. Dragonfly also apparently had a cousin who was on here as well, and this cousin made multiple threats and demands towards the rest of the forumers. We eventually found out that Dragonfly and her cousin were the same person.
Later, we had a prominent forumer called Hurricane. We all trusted her and believe her to be part of this family, but then one day we recieved the news that she had been in a car accident. The person who brought us this news was her sister, and so of course, we believed it. We accepted her sister into our family. And then we found out that her "sister" had lied to us-because her sister was Hurricane, and Hurricane had never been in a car accident.
I'm not telling all of you guys to never trust anyone online, but I am telling you to exercise more suspicion to people than you would in real life. Because in the real world, you can see the people that you talk to. Online, you could be talking to anyone.
