Please look at Goblet Ward 2. If you think that activity is suspicious please report.
All houses were purchased with a similarly named FC, all have exactly 4 members, all members are levels 1-3, all members are gladiators. Only reason I can see for this is Selling the FCs. (https://na.finalfantasyxiv.com/lodes...&gcid=3&order=)

Thank you and good luck with housing.
