I received a site violation for apparently "spamming" when I didnt even realise I was.

I tried using the send feedback option on d2jsp but havent heard back after several days.

Is there any other way I can speak to someone

If by violation, you mean a warning or suspension, then you can PM a Senior Moderator found here regarding your Warn/Suspension: https://forums.d2jsp.org/staff.php?g=30
