At present the character limits for any communications are so small and restrictive, that you cannot use eBay to properly communicate. It is bad enough that the system used removes all return breaks making the communications a giant block of words which a normal person cannot read coherently. But when you try to reply the character limit shrinks drastically. It is impossible to communicate and do so in a reasonable manner with just 99 words (500~ characters). These are generally not simple disputes and character limits only make it more frustrating and encourage bad feelings between the buyers and the sellers because they cannot properly communicate what they are saying or respond in full to claims that were made.
In fact, the character limits at all parts of eBay should be removed. If I am reporting an item or a user, the description should not be limited. I should be able to describe all the issues without having to remove important context and information. I also should not have to use inaccurate terms because the character limit won't allow an accurate description.
