What is the meanest thing anyone has ever said to you on the internet?

hi cyberslave. i used to work as a technical support agent - answering calls from customers regarding issues with their electronic products. one time there was this lady who was upset because her tv just stopped working. we tried fixing it over the phone, giving her steps like unplugging/plugging the power cord, but to no avail. i finally recommended the tv to be repaired by an authorized service company. this is where she started getting really irate and calling me names. she even told me that i was very unhelpful and i was worthless as a human being, let alone a phone support agent. well, i understand she was just upset because of her tv, but i just couldn't accept the part about me being worthless. i mea, who would? nevertheless, i still continued the call with all the will i could muster just to be courteous and patient over the phone.

It was years ago now but I still remember it, I had posted my pic up on a site and someone really criticized my photo and was nasty, very very nasty, when I looked at their profile I couldn't see a photo of them, so I was left thinking well at least I have put my picture up and you haven't bothered, but they were very nasty and it was the first time anyone had said this, it put me off going into chat rooms, even now I don't like them but it hasn't stopped me showing my picture! They weren't anyone special anyhow and if they haven't got the guts to show their picture how do they dare criticize others for putting their picture up?
