in orkut useless communities added to my profile automatically.please help!!!

Well you have option to unjoin or delete them, it happens somtimes of some nuisance link.

This happens when someone has hacked into your account, if you see new communities in your profile, dont waste time change your password immediately.

This is a very common prob in mylot People have developed scripts which can make you a members of hundereds of comm without you even knowing it. And when you chck your communities the numbers can dazzle you. In other cases they can post links to pages where you are requested to join the community And sometimes if someone has hacked your account then they join different communities with your profiles

I had the same problem.It happened to me when i had sent friend request to some of my friends.I tried to unjoin from the communities and it worked but after i logout and then login it is there again.So i got fed up left it .and after a few days i tried again and it worked and now there is no problem of automatically joining any community atleast for now.
