What exactly are you talking about? Receiving propositions in messages? On Skype? In sessions? And how often do you get these? I ask because I have neither instigated or received this type of attention, so I'm curious.
I'm a little concerned at a couple of comments which seem to excuse, doubt or explain away the original poster's complaint. If one of us is getting unfairly targeted, shouldn't we (as the italki community) be worried and therefore aiming for a solution?
There are people on here who just want to harass women, but the majority consists of people who truly want to learn your language. Please do not think that all men on here want to harass you because most don't. I am a male and one time, when I talked to another male, he said I was an evil American who wanted to harass him, just because another American harassed him earlier. I just wanted to exchange languages with him, but he stereotyped me for no reason. Don't stereotype, but if someone does harass you, report them to make iTalki a better place.
