Some raiders keep on raiding a server I’m on with new accounts

I am on a server called Hoomanz Squad and we keep getting raided like every week. They bam them, but then they just come back on new accounts. They ping EVERYONE several times, once I got pinged 145 times! I need help getting them to stop. Please stop them or remove them from discord, here are some of the raiders IDs:
