Profiting at the expense of the state

I would say "being taken advantage of". For example, when 揩油 is used in a scenario whereby a girl is suddenly hugged by an unknown guy who is doing it intentionally, we can say that she is being taken advantage of. I wouldn't use the word "molest" as it carries too strong a meaning. Any comments from anyone?

What is the context, if you use this in a sentence?

scrounge -getting something without the intention of repaying

No way to say that in English I guess..
