<…> It doesn't seem right to me if an account that has been grown with so much efforts upto a hero rank and it will be abandoned because of death.
I think sure account is worth inheritance and could be passed to relations left behind.
I beg to differ on this one. An account has a lot to do with the person that runs the account. Having the account run by a second person after death, though technically feasible, could seem rather odd and even potentially deceiving, since likely the former owner and the, lets say heir, are likely going to differ in ethics, style, knowledge and interests. An account on Bitcointalk is likely not going to be top of mind amongst the things to deal with in the aftermaths of one passing away though.
The exception, perhaps, would be a business account, which one might want to keep on running after the owner passes away, although here we are potentially walking on a tightrope, since the reputation built by the former owner, and associated trust (not strictly speaking of the forum’s Trust here) were earned by the former, and one wouldn’t want for it to be abused or side-tracked by the latter.
I'm more in line with the idea that people should create their own account, and not mess around with buying/selling/inheriting for the most.
Edit: It would be nice to get an update
on this analysis I did years ago, but I lack the data. Amongst other thing, it showed the number of "abandoned" accounts per year and/or rank, though obviously not the reasons.
