When FFXIV implemented better blocking tools this past summer, there was an option when blocking a single character to block the entire service account. This would be fine, but the implementation they went with is client side, and when you select that option, you get the service account ID. Which means that if you’re blocked by someone, you can’t made an alt character to stalk/harass them. But with third party tools, we can see this account ID. The stalker could just use a new account and find the person’s account ID that they were harassing and find any alt character they have in the game. They’re changing this soon as a third party tool popped up and is now able to do this, full source code leaked so there’s no shutting it down until the game devs change how it’s done.

This sounds super similar, but the implementation that you had to do for google is crazy.
