While they've got their little traps scattered around the game world for the usual RMT farming bots, I don't know if they have any detection for those involved in housing. Reporting their specific activity could be helpful to the STF.

Except you couldn't have 4 characters on the same account all online at the same time so we know there are multiple accounts involved in the OP's example.

SE has said they're working on updates to FCs but it's doubtful that those changes are going to impact shell FCs in housing since they'd be just as likely to harm small but legitimate FCs as the shells.
