Sceadu, idk.. 1month is not much time, for me.
In my case i use to travel a lot, two years ago i went to Cuba on Vacations for 8 months, no internet there, so i never logged any of my characters. Went to Miami in September, staid a month, hasnt got internet there whit my company so couldnt log ws too. Idk idk.... as Jamie said only "empty" characters. The ones who looks full of items,has to be keeped.
Plus, lets imagine i don't log my bank "Cosita" for 1month, so another people take it, maybe a scammer, why not... using my name he will be able to scamm so easely everybody becouse most of the people who thinks its me could trust immediatly..
I'm agree on just low lvl, no actives whit empty bag etc.
My bank as example : shaman lvl 3, using costume; hair style, hair colour, novice set, full bag open, has items etc. Im for a NO to the delete thing. And also for the change name stuff.
