Economy Server Crash issue

I hate to say it but today has been very rare on crashes as a certain player wasn't on, nor his alts. Staff know who this player is with his 4 islands all linked and a massive spawner farm linked on 4 islands.

 

Both asivator's and vvyovx's alts were offline for most of the time I was online today and server TPS was around 15+, although not great it is definitely better than the usual 8-10. However as it did crash once that proves that there is more to it than just these players but they certainly aren't helping.
