Yeah, you're confusing "it's legal" with "it's not a depraved waste of one's humanity praying on the weakest of society".

That should be wholly obvious from the fact that these sites exist, out in the open. And from the fact that nobody argued what you're refuting.

(It's wrong, obviously, and such practices should be illegal, as they are in every civilised country and then some. But that's a separate matter)
