That's an interesting request.  Most network operators know about AS  
adjacencies, since it is hard to be on the Internet without your AS  
having a link to at least one other.  Do you expect everyone to ping  
you back?

Also, what makes you think all adjacencies appear in "public available  
BGP tables"?  Most do not.  This is not surprising, it is expected.   
I'm interested to know why you think they would.
