Looks like Pathra made a video on that one stalking article: link

Some of the top comments on the video:

"My former best friend had this issue, being stalked by someone that was formerly in our FC, and it got so bad, right around the time Oceania DC opened, that she xferred there to try to get away. She couldn't do anything in peace if he was on at the same time before that. He thankfully didn't follow her there. It also doesn't help that your Lodestone page URL will remain the same, so if they have it they can constantly see your character, name/race changes and all. It's sad to see the really pitiful excuses as to why it is the way it is, when the way it is ACTIVELY helps people be stalkers."

"they really need to fix the issue that if you change your character's name it should change the lodestone character URL # . if your stalker has your profile bookmarked, no amount of money spent on fantasia, name changes and server jumping is going to remove you from being targeted."

"I just went through this recently, despite blacklisting 2 individuals, they both decided to hangout in my house and leave messages in my book after I made it known I didn't appreciate it. This went on for months, I tried contacting a GM multiple times and had no luck, just automated responses. I ended up moving servers in hopes of a fresh start, and a mutual friend confirmed they knew where I transferred to (they still had me on their friendslist). So my main of 5 years is doomed for future harrassment... I had to reroll :c"

It seems to be a common problem unfortunately.
