communites online..?? r they safe..??

i generally use the orkut and i think it was fully saved to do work on it.

According my mind, if you don't share your personal information on communities then you are safe, big problem is that peolpes makes new freinds in very short time, then they get phone numbers of each others, when meet in real it may cause of problems, other wise communities are best if you don't have friends in real life or other wise you can't trust peoples. Safty tips:- 1- Don't share any personal information such as home address. 2- Don't share your personal phone numbers. then you will be safe and enjoy!!!
