Hello again! I've been looking to your ban system. No offence, but you are disrespect your own work. You can not cover 10% of the reports from EU 1, 2 and 3.
In several topics I saw comments that suggests and encourage recording and manual sending the video to an admin. This can work if everybody recording. As MCSA I won't recommend that if you have an HDD. (TTL reduced to 300 days ...ish) Your specs will go off the grid, and the game performance will be poor. (low fps if computer is rated as 7.5 or lower)
Why don't you create a report system, based on server recording? You can set wide area cams all over the map.
Example>
Some player ram or block... on A10. I make the report. The server record constantly that road. When it gets my report, server will save that 30 seconds video, together with the proper identification of the player reported. (steamId and other). The administrator will access the video, and make a decision. After administrator close the case, the video will be deleted or place as evidence on youtube.
This way, nobody will get away without the proper punishment. I know it's complicated, it will take a lot of time, but it's doable. Do this and from that 10% efficiency, you will gain 95%. (Some players choose not to report small infractions).
Thank you for your time.
