Should there be concern?

Recently I ran across an item of interest to me here on audiogon. As I read the entire ad I found it strange that the condition of item said new but the limited informative text said it was used until recently. I send the seller a private text regarding this and the limited information suggesting he should change and add more information.  I received a nasty reply and was promptly blocked by the seller. Would this raise red flags to anyone else or am I just being too sensitive?
