We use the Main Stream Gamers' PunkBuster Screenshot Viewer. Then you can share the link with your clan and they can help review them.http://www.msgamers.com/pbssv/
It is much easier to view them on our NFO webspace and then let the auto websync work. If we need them sooner I just force a websync but we never see lag.
We've taken 55,000 SS's so transferring with FTP takes too much time.
You have to go back 215 bans to see a ban for a screenshot, I don't think they are as effective anymore.
We have very active admins plus we just block the countries that offend the most, ex. Russian federation.
