I also understand wanting to delete specific posts one has regretted writing. I can delete individual posts given a URL for each individual post.
However, in the past year or so a really bad trend has started on the forum with people asking to have their entire account and all their posts wiped. Reasons vary. I understand why this is an easy solution to the person requesting it, but please consider the damage it does to the rest of the forum. When hundreds or thousands of posts disappear, it leaves conversations full of holes. People are still shown responding to past posts which are no longer there. This can be both confusing and it also risks changing the perception of those on the other half of the conversation.
Deleting an entire account doesn't happen in a vacuum. It affects other people and so it's not a decision that should be taken lightly or out of convenience.
I don't want to say that wiping all posts will no longer be an option because I do think that ultimately people have a right to get their writings taken down. However, insofar people don't want to say something "for the record" I'd strongly suggest not saying it in the first place rather than clobbering it later. There's just not much point in my spending time moderating and curating a forum if thread-coherence gets regularly damaged. We might as well have these conversations on snapchat

For those who for some reason want to leave the forum or be prevented from coming back to curb an online addiction or for whatever reason, I can also delete just the account and leave the posts. This is my preferred solution for this kind of exit.
This is kind of open for debate because I'm not sure what the best position is on this. Currently the forum feels like a team work with the goal of providing lots of informational value. It's thus not great when someone decides to leave the team and "by the way please burn all my work as I head out the door" leaving the rest hanging. I think this should be an extreme case rather than a regular one.
