It puts it in the same conversation, so it must think it is, and therefor its presumably not unsolicited, even if it is unwanted? Sadly, whilst gmail gives the option of marking mail as spam, it only does it for the first email in a conversation, so the user can't even train it (assuming that gmail can be trained.)
