Unless its a genuine mistake, And i believe this is what happened to this particular thread, Then Threads can only be deleted if the member gets in touch with IanB and he authorises it, He wont do it very often as it removes every thread ever started by the member. It also leaves holes in the threads they have commented on, From a moderators view there are issues with this new platform and one of them is the ability to deal with the same couple of people who only come on here to cause shit, Ask yourselves the question, Why are so many moderators not active anymore?
