should SE delete characters that were never used

[Rowyne]

Or even better, just force them to change their name upon attempting to log in (which they likely won't, if they never got to level 10 and haven't played in a year, their more than likely to start a new character)

There are some MMOs that have done that in the past. If you haven't played in a certain amount of time, your name is up for grabs and you're prompted to change it upon login if someone else has snatched it up. If you haven't played in, say, a year, then I think that's fair.

Character deletion, however, I don't agree with.
