we're working the bugs out of them now. they should be much easier to use by tomorrow afternoon... i hope.
people who used to sit on the same photo/profile and post the same comment, quickly, over and over will need to figure out something else.. as that probably won't work anymore. don't come bitching and moaning to me either, the comment features were never intended for that and requires massive amounts of our resources to let you do that for no one's benefit except your own. if you want to run a contest, do something else... like measure the number of ratings a photo/profile has received.
also, we can easily detect people running third-party programs to automate the commenting using the old system. congratulations on violating the rules of the site by cheating and having your account removed in the very near future.
merry xmas! :-)
