There are savage and ultimate raid clear selling ads clogging up party finder urging those interested to communicate via Discord all the time, and it's common knowledge that those clears are being sold for real money.
TOS update is on the way to combat this.

It's common to see hordes of bots teleporting through main story quests, and this is especially frustrating when we're experiencing such intense congestion with Endwalker around the corner.
These are disposable accounts farming gil. They exist in pretty much every 3D MMO (gilfarmers exist in 2D MMOs too, but they don't teleport as often) and get banned fairly quickly.

Finally, the reporting and penalty system needs an overhaul. I understand the necessity of being vague enough to allow reporters to remain anonymous, but it is impossible to avoid repeating a mistake when you don't even know what the mistake was to begin with.
This is really only a problem because of the permanently escalating nature of infractions. GMs should be able to use discretion in suspension times and look at things like how long ago was the last offence and how many account actions have been recorded in total. This throws the truly toxic people, who try to game the system, out of the game while keeping an occasionally tripping player outside the permabans, without being too light on them.

It seems strange to me that very obvious phishing links aren't blocked (if the link contains "forum.square-enix.com" but has something else tacked onto the end because it's not actually a .com domain, for example)
They do eventually get silently blocked, but the domain is constantly changing and you can't really make an intelligent word filter without risking legitimate messages being blocked.
