Set of vandals I'm currently tracking (suspected to all be the same person):

68.97.135.154 ( contribs)
Assdog137 ( contribs) (A shoutout, I think?)

Pages they've (/he's/she's) been vandalizing:

Windows on the World
American Airlines Flight 11
Diesel engine
Marriott World Trade Center
List of tenants in Two World Trade Center
Norman, Oklahoma
Stillwater, Oklahoma
Nintendo DS Lite
PlayStation 3
Wii
iPod nano
AbeBooks
My user and talk pages

And he/she/they harassed this poor user with a vandalism warning for reverting their vandalism:

90.241.42.46 (...although they didn't sign their "warning").

Any help catching other vandalism by this user would be appreciated.  :)
