I have been dealing with someone who has been over the last few weeks destroying parts of my buildings, like walls, usually nothing major.

But today I log in and an entire floor is missing, this is getting ridiculous. I have an area on the zombie server with 5 sponges, so this is apparently hacking. Please see the attached screenshots.

Thank you.

Sorry for the inconvenience, I'll look into this now.

how do i get a sponge on this server?

There is a sign at /spawn that allows you to purchases them.

This is nothing new

It's not hacking it's a total derp glitch in the plugin where the sponges do NOTHING to protect areas. I thought yield knew about this as afew mods have delt with incidents like this and said they would tell yeild....

I think it is all sponges do nothing, not just afew. My base was griefed to shreds recently just because of this bug...

As a matter of fact, this was a case where a person who was on the allowed list had there account compromised. Damage was repaired. However I have seen a couple of buildings on the zombie servers with tons of these sponges all over, I mean dozens, peculiar.
