Actually it's probably from a person called NekoSenpai (profile here:
https://forum.square-enix.com/ffxiv/...873-NekoSenpai), who has been harassing a lot of people through thread tags. They are most likely the same person as RaenMan, who accused Macchi of being a pedophile, and they admitted to mass reporting people if you look at their post history. By the way they are someone from 4chan, and is part of the anti-Trancer faction. Yes, you heard that right, for some reason they are still waging the Trancer war when no one even cares anymore.
Funnily enough, whilst accusing others for ban evading in the thread tags, they themselves are ban evading. NekoSenpai is their third account, if not the fourth or more. And dare I say, they are remarkably active on the forums. They put up these thread tags mere minutes after a thread is made, at any time of the day.
Even more funny - just one or two minutes after I made this post, they removed all their harassing thread tags.
