I am part of TBB, and someone there came up about this. This is what they said

We have found an E2 that acts as an infectious virus. I don't know where it originated from, but it's quite complex and seems to travel through adv dupe, both 1 and 2.

I won't include the code itself, nor how I found it. I don't want to unknowingly let the creator know how to prevent people from finding it. But the E2 is named CryNet bot and appears to try and constrain itself, and already spawned copies of itself to anything which may be duplicated or multi parented using no collide constraints. It's fairly complex code involving global tables and finds. I don't really understand all of what it's doing.

I'm posting this here as a PSA to server owners. Maybe we'll be able to figure out a cure for this.

Sorry to bring this nice discussion about alots down, but I figured it would be worth mentioning to you guys.
