A couple of people on #unix joined with fake names to take a look around and generally get in the way. (One was Jesus Christ.) To no-one's surprise both were suspended, but it turns out that their UIDs were both later reused for new users! As if this weren't enough -- what if you suspend someone accidentally? -- it turns out their deletion doesn't work deeply, and those new users who inherited the suspended accounts' UIDs also now have the (offensive!) communities that the #unix guys created attached permanently to their accounts!
Not a chance that this stuff is directly Google-run.
Also, I just checked the owner of the network that Orkut is located on -- it's on the /28 Cogent has allocated to Weather Underground, and not in the /19 directly allocated to Google.
Even better: You can see in their Netcraft entry that the server, which now only returns "orkut", originally returned "Orkut's Palace of Love". Well, colour me disturbed.
Edit: Some other findings thanks to #unix:
<cstone> fans, interestingly, are tied to username, not uid <cstone> when i created another account with my original username, i got 16 fans instantly <Mennonite> I already tested making new accounts with dodgeit <Mennonite> You can "recycle" the same invite URL over and over <cstone> i'm certainly not going to bother refriending 50 people again <cstone> when they reset it briefly all of that state was lost in the account i took back [from the reused UID] <mr_bill> BOFH community (-6 members)And cstone still has a session open as the UID that was deleted and then recreated, and can change the new user's password out from under her.
