EDIT: I'm shutting this topic down. I gave up on keeping track of this ages ago, because it just got too depressing for me and besides I couldn't keep up.
People keep sending me messages asking me to take things off the list insisting that so-and-so isn't dead. If you have successfully revived something, congratulations. But this list is now a historical artifact and I'm not keeping it up to date. Nor am I interested in debating what "dead" means in terms of a block chain coin.
Usually it turns out that they are just reusing the name of so-and-so, which is, yes, still dead. Alternatively, they may have a live block chain of so-and-so which still does not appear on the significant exchanges, or which has still such an insignificant market value, that it is, yes, still dead. And these points are just too tedious to debate and I don't even have time to research them all.
There are also messages I find particularly depressing, or which make me angry, and those are from people who are digging zombie so-and-so up for one more lurch around the gravestone, in a necromantic version of a pump and dump scam, using the fact that "so-and-so has been around a long time" to reassure their prospective bagholders.
Anyway: To everybody reading this list: These coins were what I considered dead, at the time I was maintaining the list. Some of them may not have stayed dead, and that's okay. Some of them may be in the hands of people now pretending they aren't dead, as part of a scam, and that's not okay. I'm not going to help you decide which.
To everybody who has something that appears on this list and believes it isn't dead: That's fine. Maybe it isn't. I am not updating the list, so consider this as information about its history, rather than information about its present.
