I may be asking for much, but wouldn't it be more appropriate if the user had the option to choose not to display any activity at all? For example, if you were inactive for 73 hours, display "(Not recently)" instead of "June 09, 2024, 08:40:33 PM". Or just "(Hidden)" regardless.
Someone might want to take a break without letting anyone know about it.
You see, i don't think the sole essence of the modification was to blur out the system entirely... I think it was more about blurring out the exact time a user is/has been online, thereby creating some level of pseudonymity - I may be wrong, but if it goes your own way, everyone knows you haven't been on - That doesn't really differ from what we had.
In this Case, Nobody knows precisely if you're online or not; The display word "recently" does a two-way job.. it could mean the user ain't active, it could mean they are...
