It has happened to someone i know online though I've not met him before. The way he act and respond online shows that he's drowned into the well of depression. According to my research, all this act is due to his recent marital status that didn't end well. When he's depressed, he has no option but to come online and disturb people's peace, all with the aim of getting attention and exchanging conversation.

Hmmmmm.....I was once had a kitty/cat that normally behaves that way. When he's depressed due to loneliness, he'll go around the street looking for young and old cats's trouble. You know what i did to stop all those childish behaviour? I bundled my kitty inside a cage, he slept off, and kitty couldn't wakeup again.
