I've added these two ads from Backpages, not because I think these 2 potential providers are particularly attractive or forthright, but to demonstrate something.
Writing "By CaLLing YouAgRee ThAt U R NOT afFilIATed w/Any LaW enForCeMenT agENcyˇˇˇˇ" or something similar on an ad amounts to nothing less than a waste of time. It's not a contract or some type of legally binding agreement. If such warnings held any weight then drug dealers would simply tell crackheads "by asking me for crack you are agreeing that you are not part of any law enforcement agency." These type of warnings tickle me and are utterly worthless. There are things to do to keep you off the radar or help your chances from a legal stand point, but these warnings are not one.
Side note: Why do both their ads state "No black men"? That's a little upsetting.
This is not legal advice, but the humble words of a well-educated man. I'm a student of the world and love when she's the teacher.
