Well, as you can see, the wiki definition is so big and broad I wanted to know what this forum considered shilling and what the rules were. I guess the *impersonating any person or entity which could then lead into *posting advertisements... is what I understood in my silly mind to be one form of shilling. Thanks for the help.
I searched the word shill but found nothing. It turned out to be a bit more of a complex question than I originally thought.
EDIT: I see posting false information, is also included there.
