Yeah, it's very dependent on the kind of fame, as well as the field you're in. A major kpop star/Japanese idol is probably going to have all the problems in the blog article, perhaps magnified by ten. Their fanbase tend to be... a tad less on the sane side, and there are a fair few of them who are absolutely obssessed with their idols and will resort to stalking and harassment.
But at the same time, there are plenty of fields and claims to fame that won't get this. Researchers will get less of it. Someone who doesn't show their face online will seemingly have less of these issues (though people might get obssessed with finding out who they are, ala Satoshi Nakamoto and Banksy). And those focused on more technical/specialist fields may have less issues. Your average popular YouTube glitch hunter or speedrunner will have less problems than a popular YouTube political pundit.
