Plus, SE made it super easy for people to own multiple single character FCs. So blame SE for that mess.
Not only did they create a housing system which can not support the larger servers (and only the larger servers as the medium and small servers still have plenty of houses) they created a system where only FCs can have access to a very lucrative part of the game (airships and subs).
Instead of attacking this player, just implore that SE change how housing functions, give all players access to airships and subs, and move the workshop to the company barracks so there is no need to own multiple FCs.
Whether or not you agree with owning multiple FCs, SE has already shown they will grandfather anyone currently owning a house or multiple houses into the new system.
Remove the desire to own these FC houses, attacking the player on this forum only makes people look like jealous children.
