The Op posted his ad and clearly mentioned the pricing. You then posted and asked him how much. You need to read the posts in which case, you neednt have posted. If we did not moderate these types of posts we would have threads full of non interesting garbage. So according to the guidelines it was deleted and you recieved a warning. Please note it was not an infraction, it was simply a warning\instruction not to make that type of post.
I appreciate you contacting me, it is not a huge issue so do not be overly concerned or anxious about it.
