This is something I've been thinking about since joining Stack Exchange a few years ago, and is something that might worry me about the future authenticity of answers.
Does Stack Exchange have any way to detect, mitigate, or otherwise stop people from handing over their account to another person?
The implications that I can come up with are many, and there are still more that I'm sure that I haven't thought of. The most concerning problem that arises from such a scenario is that this person could potentially take actions that they otherwise wouldn't have access to such as providing bounties, creating erroneous tags, meaninglessly down-voting questions, etc. If the errant user has enough reputation, they can even edit posts and gain access to trusted user tools for deletion and un-deletion.
Is there anything that can even be done in those situations or is this just "the nature of the beast"?
Edit: In reviewing the suggested duplicates to this post, I suppose the question should just focus on transferal of accounts due to any reason, instead of death in particular, because there are many ways in which someone might come into possession of another's account, and specifically focusing on just one aspect makes it harder for future users to research questions like this.
