There will definitely be some in the resale in April. Sometimes they pop up randomly as there isn't a balance payment issue so they seem to be batched together as people get refunds.
So what's easier, to let an individual who understands their own situation decide on what they share and what not, or regulate a complete forum that anyone can access, that random people can visit any time, and determine what kinds of questions they can ask? Come on. Leakers are adults, who know perfectly what they can share, what the level of risk is, know their own circumstances, etc.
