Ok so looks like people are still taking advantage and getting multiple houses.

Because it's not the same FC.

A FC can only own a single FC house.

It's different FCs using the same <<TAG>>

FC tags are not unique.

That's interesting - I've never (until now?) encountered obvious duplicate FC tags in the game, so it's surprising to discover that they are not unique per server! I imagine that might cause some confusion between different FCs that pick the same tag, either intentionally or accidentally.

So this is ostensibly a confederation of FCs operated by a single entity, one so shameless and untouchable that it flaunts its power by using identical FC tags and buying an entire ward?

Seems like maintaining all of those FCs to avoid losing the houses would cost a lot of money in subscription fees.
