What do you think is cheaper... implement a filter to identify "unsavory" words and then have someone literally review EVERY hit to see what is "acceptable"? ...or implement a filter, insert the "unsavory" word into a form letter, delete the listing, send the form letter to the seller explaining "how much they care" about their membership?

Pick a new word: actionable, banned, black-market, bootleg, contraband, criminal, crooked, extralegal, felonious, forbidden, heavy, hot, illegitimate, illicit, interdicted, irregular, lawless, not approved, not legal, outlawed, prohibited, proscribed, racket, shady, smuggled, sub rosa, taboo, unauthorized, unconstitutional, unlawful, unlicensed, unofficial, unwarrantable, unwarranted, verboten, violating, wildcat, wrongful... enjoy!
