We've had serveral days of sonic interference on slaybox 2. On SB1 we use a mod that auto-mutes micspammers after X seconds. This has been installed and enabled on SB2.
Essentially those who use 3rd party programs to spam their bad taste in music will be muted after 7 seconds. It does not effect those who use normal chat. It does not effect those who have voice_enable 1 turned on. Only those who use HLDJ or HLSS. And only those who have something recorded over 7 seconds. Short clips are A-OK. Anyone muted can be unmuted by an admin. The mute only lasts until map change.
This should solve almost all problems due to mic-spammers. And no need for an admin to jump around ruining his slaybox fun.
