It isn't just you and as a burger king crown wearer let me tell you that you can get it purely by just playing long enough almost no matter what you do.
Moreover, there is absolutely no incentive nor requirement to maintain or keep it by helping others in some way because actually moderating that beyond pretty basic flags or checks for having done something is both something Squeenix is too lazy to do/doesn't want to spend money or time on as far as having someone look at that. Pretty much impossible to automate so the current system is what we got and will likely always have.
Personally, since I'm wearing it I just try to give decent advice when people ask for it and play as well as I can no matter what job I play, but many, many experiences with other people who wear the godforsaken crown have taught me that, much like you, I shouldn't really be expecting much. And in fact, should probably be expecting even less. Still, after having played this long, I don't really let it bother me that much anymore. It tends to usually be a pretty minor annoyance in the grand scheme of things compared to all the other things in this game that do a better job of getting me upset.
