having spent some time editing wikis (and adminning a couple, back when "wikia" existed) i do understand the webmaster's frustration. if someone wants to troll, there's no real way to stop them. blocking their account is worthless if editing doesn't require one. ip blocks are worthless because it takes two seconds to change your ip.
i suspect steven black hit their limit and decided the time they were spending rolling back the troll's edits were better spent elsewhere. i don't blame them, but it is a shame they wouldn't simply make the whole wiki read-only so the resource isn't lost.
my answer to this thread is: outpost gallifrey.
i never got an explanation.
outpost gallifrey was the second-biggest doctor who forum to ever exist (the bbc's official forum was both more populated and more active, but they made the incoherent decision to shut it down just before the 2005 revival was announced).
according to someone i used to follow on livejournal, the exact date of the shut-down was
31st july 2009. not going read-only, no archives, the whole site simply vanished overnight. they wiped the database and let the domain expire.
my internet access was heavily restricted between 2009 and 2013. for much of that time, i had no access at all. og must have gone down only a few months after i lost access for the first time. what horrendous timing.
2014 was a year of discovering so many of the parts of the internet i used to live on didn't exist any more, or had changed so much that they were no longer my home. but the loss of outpost gallifrey was the worst of these. it was just gone, with no explanation.
thinking about it now still makes me feel that same hollow sadness. when i first learned of this, i also felt angry and betrayed. i had lost so much. so many friends, so much history, so much just...gone.
i still have no idea what happened.
