I deleted a 10+ year old account a couple of years ago. The accounts I deleted when the ruckus started were those I'd been using since then.
That 10 year old account a couple years ago bugged me awhile because I had the conceit that anyone at all on Reddit recognized my name or cared what I had to say. Eventually I got over that.
As a result, I felt almost no sting from wiping and deleting the younger ones. Maybe 5 minutes of feeling a little weird about it until I realized I'd given up exactly nothing.
