I moved your thread to a more appropriate forum. As for your questions, we (for some reason I don't know why) allow you to make threads about other users as long as they aren't negative in some way. Just because a user is banned doesn't mean that thread has to be locked, but creating a thread specifically about that user being banned is what gets locked. If you link to a thread that ends up getting locked, there is probably a good chance the other thread will be locked as well. That would be on a case-by-case basis depending on why the thread was linked.
