HELP with A Modpack

Hello, I have been playing on a minecraft factions / anarchy server for the 1.7.10 pack and I got into some trouble by nuking another player by accident (Kind of). Now they are going to use witchery to tp to them and use a machine to drain my Items from my inventory and TP me back, so Ill lose everything. I almost got raided so I put everything I owned in dollys and Golden Bags of Holding. Now they are going to try and drain my inventory, does anybody have an idea of what they are doing or how to stop them. (Also they are a vampire) Please Help!!! also the Inventory drainer works in proximity not direct contact.
