I registered there couple years ago and was looking for friends while traveling abroad.
I thought people go there for the same reasons. Or to find hosts, help foreigners with housing, cultural excursions etc.
As my experience showed, this website is mostly for men, who are looking for sex or escort, which wasn't ok with me. I wrote it on my profile even(guess nobody reads that)
I didn't expect that I would get to know some jerks and rude men there. I press the button "to ignore" them and it's okay. Maybe support team could somehow pay more attention to such profiles and eliminate them. Because rude manners and behavior online is terrible. Some of those guys treat girls as sh*t. And it's not okay, I think.
Though, it's great that not all of men there are so. I found some really nice people: girls and guys with whom we're friends through the years.
So maybe it's not a best site among travel sites, but not the worst and you can try it.
