think it was just a spam?

I think with every sort of socially interactive media, the desire for romance has to come up at some point. The same went for Interpals - a place where language exchange is the theme of the site. People would send flirty messages to each other, and girls were naturally hounded by a tide of men who would send them suggestive (and sometimes simply pornographic) messages. It's not really italki.com that becomes this, but rather the community that grows up around it. Give people profiles and pictures, and there will be creeps at every corner. Such is the way of the internet.

Click onto her profile and see whether she behaves in the same way with others. Yes it could be a spammer. No, Italki is not a dating site. Anyone who feels offended by this sort of behaviour can report the person to the italki administration, especially if this woman is a spammer and has just copied/pasted the same thing to other guys.

haha, I had the same experience, but usually I politely brush off those guys who are too "pushy". But if you have some sympathy towards that girl- why not to start closer relations?! Such things can happen at any site, no matter what was the first purpose.

haha maybe she liked your mind . because the beauty not everything
