In comparison, I haven't had as many requests due to the nature of the thread that you made, but I've whitelisted 0 currently. Although, I haven't been actively reviewing it every day as I decided it would probably be better to add a gap to see how serious the user is, I did catch up with a few requests, and most never got back to me at all. Probably looking for a quick solution. Unfortunately, my methods probably are a little too robust, but as theymos says most users that hit the fee are for valid reasons,  and in my mind its up to them to convince me.
