Been a hot minute since I've posted here, but looking back some of my threads are rather embarrassing and I feel reflect myself poorly.
Is it possible to request a few of them deleted?
We generally don't delete threads that had other replies unless there's a good reason but yeah, it's probably better to just ignore them. Nobody is going to look for them unless you go out of your way to point them out.
For most people, time is too precious to look after old cringey threads.
Unless you're a politician on Twitter, don't worry too much about your old stuff.
And dude, don't loathe yourself in your own user title, avoid this kind of negativity in your life.
