Its not only in qatar, its all over the world... but i would like to ask u one question, if u don`t want to have talk or chat with particular person then firlst u should warned him and second u may contact QTEL or POLICE so that person will not disturb u... this is the time that girls have to take action so men will not think something... but sorry to say i can see lot of these kind of girls also and even they will make friendship only for the money... so all the way there are men & there are women... so no need to point on anyone.... just take action and then these things will be stopped....
