Victoria, I've been following that twitter conversation, and I saw one agent mention that this language was actually in THREE agency contracts...all respected agencies. Would you happen to know which other two agencies they were referring to? As you said, this is all technically above board and not implicitly unethical, but its implications as to the agencies' priorities are not ones I'm comfortable with and I would definitely like to know of any other agencies utilizing such clauses before I query them, wherever possible.
