A friend sent me an email telling me my site has been blacklisted by Google – largely because some spammer (die, spammers, die) hacked a message and put a bunch of link spam in. I really have to question the security of wordpress. If they can’t keep it clean, I’ll have to migrate to something else.
There is an interface to request removal from the blacklist, but while you can be blacklisted in seconds, it apparently takes several days to get off of the blacklist. Nice.
