I just spent tonight getting signed up for WPMU sites. (Word Press Multi User) I had a list of a couple hundred and I think I managed to get 15 accounts. Seems most are offline or have disabled accounts. I can only imagine how horrible the spamming was to get to this point of making the platform practically obsolete. When was WPMU's hayday? I was hoping to start churning out the content with links, but I guess not.
