But
InnoGames is located in Germany and they say that European law regarding privacy will not allow them to add this feature.
TBH, I do not believe this. I live in Europe, not Germany though, but what I see is Inno using this privacy law as an excuse for way too many things, including the one specified in this thread, not to implement them. As others mentioned and posted screenshots, in forum you can opt to let others see if you are online or not, what content you are reading. So can be in a FS. If an unknown player called MataHarry
decided that her privacy will suffer because the AM will know when she (as well can be a
he) was online last time, she can always opt to keep that invisible.
The excuse of the Privacy law is thin because in the Rules is specified not to use your real name, to use a nick name. By doing so, me, the player named Alcaro, I assured my own privacy. Alcaro doesn't point to anything, doesn't suggest any place where I could live, doesn't point out my gender, my ... anything. All you can see is a cute dog
named Alcaro. Soooo, if you know when the pup Alcaro is online or was online last time could possibly hurt me, my answer is Definitely Not.
Bottom line, the developers do not want to bother to implement any tools what an Archmage should have. Invoking GDPR is simply a bed story for kids.
