That is weird. 500px.com has a setting to indicate if a photo contains nudity, sexually explicit or suggestive content and I have not ticked that on, but you might be right about the title. I like your suggested name, but I think the link has already been cached with the title, so changing it might not help.
Weird...my company blocks 500px.com...maybe it's your title...maybe rename it Butterflirts.
