Way, way back in the day I remember quitting my short-lived stint in FFXI and being told that my account would be deleted if I didn't reactivate within 30 (?) days. Was fine by me and really just served to make sure I was never tempted to return. Everquest is doing server merges and some people are finding out that they'll lose their character name to people who haven't been active for over four years. A constant debate in the City of Heroes community is name purges and whether some trial account that hasn't played in 4+ years should be locking out "Patriot Girl" as a name. Or if a level capped account that hasn't been played in 4+ years should lock out "Captain Liberty".
Generally speaking, what are your expectations regarding defunct MMORPG accounts? Should they remain pristine forever? If you came back to a game after a couple (unpaid) years and found your characters needed to be renamed, would it result in an instant ragequit? What about after a year? Does your opinion differ for a lvl 3 character versus one that's at the level cap? Or halfway to the level cap? What if they deleted your account entirely (with notice)... would you ever consider returning?
