The thing is, how would the companies know you're paid to do this, instead of perhaps just being an overzealous employee? Not like this service is going to disclose who is working for them...right?
I imagine it becomes obvious if you file 1000 of these a month, not to mention probably many of the people wanting this service were blocked legitly, so its more likely bad requests will be filed.
Not to mention it is like any crime - not like murders intentionally get caught either, but they still do.
