Doublepost happens when you go <BACK><SUBMIT> by accident.
Unless there is a very special case, which could cause harm (as defined by our wonderful sysadmin), all posts (even edited) are fully viewable for all eternity.
Which means some time in the future, someone WILL see me making an idiot of myself calling you names.
Hopefully it won't be when I am interviewing for a position, working for someone who knows you.
