I have searched around meta but did not find much information regarding the dissociation of posts. I, however, happened to stumble across this faq question, "How do I remove my name from a post, in accordance with CC:WIKI?" which clears a part of my question regarding how you'd dissociate a name from a post, but there are still a few questions which I did not get clarity on. They are:
What are the conditions for a post to be dissociated from a particular user? I'm guessing that just any post cannot be dissociated, because if it could, then everybody who happened to post a question/answer which got a lot of downvotes(for various reasons) would like to get that dissociated (rather than delete it) so that they don't keep losing further reputation from it.
The next question derives from the first. If the dissociation is just allowed like that, is that going to affect the ban-system? Lets say, a user posts a few questions/answers and all get downvoted heavily. The automatic ban system kicks in and bans the user from posting further posts. To avoid this, the user might get those posts dissociated from themselves to avoid the auto-ban and keep posting. Although it may not happen that frequently, you just never know.
So is there any concrete documentation regarding this and if not, I'd really like the answers to the questions posted above to be used as a reference for later.
P.S: There could be more to this, and anybody having any more questions can pitch in so that we can make this a good reference for the future.
