I doubt that it would be that easy to get others documents. Sure if you are in Colombia or something and people are starving, offering a few dollars to them would make their life easier and that would be a lot better for them, it’s really easy to understand what it would look like.

But, if we are talking about something that is dangerously risky for the people who do it, like literally getting caught levels? Then it would put them in danger and people who are doing that type of illegal stuff wouldn't want to be in there. Even giving others documents would cause them to get caught if that person speaks, and you may feel at ease for 1000 of them not, but one of them could eventually and that’s a risk.
