Do not ban people or kick users who you can't browse from most are still shareing but are not listing files all at once or are busey listing files to other users and their slots are full.

Here is me as an example: I share over 150 gigabytes, but I don't let people browse my share list for because it would flood my machine and slow my already slow internet connection (2000/128 adsl), and when I would allow viewing of my shared list some people would to download too many files despite the full slots and or try filling up the que list not letting anybody else have a chance in line to recieve files from an single user.
