Is there an ability to add an audit log or something similar which shows previous names of the thread? I think this would help avoid people selling accounts and reselling them with no evidence of prior sale existing. We used to rely on thread titles before if people edited the thread body but if people can edit thread titles themselves now. They could just erase the entire title and put something like "sold" leaving no evidence of what was actually sold.
Good update though, helps reduce a lot of unnecessary reports.
