What is the ruling on love between a young man and a young woman over the internet when their locations are distant, and is it true that there is no harm in it as long as it does not develop into obscenities?

"Conversing with and forming a relationship with a foreign woman online is forbidden (haram). It is among the steps of Satan to lead a servant into immorality. A Muslim must fear his Lord and sever all his conversations and relationships with foreign women."
