I'm not sure that they don't care, or if the issue their support staff is spread so thin that's easier to dismiss stuff such as this. Who really knows besides SE?
I do know that the people doing this think it's funny and cute, like the guy mentioning that it's his
'favorite museum in Eorzea'. It's exactly no coincidence that this person is listed in the greeting section of the offending plots placard as the "
curator", right? I mean, it just boggles the mind that there are people out there who giggle over stuff like this.
The person that won the plot affected by this madness waited 3 years to win a plot. This has to suck for them. But for people like the guy in this thread tittering about his creation, it's some kind of achievement to harass someone. Truly boggling.
