I think it's kind of weird to ban them? I found a couple of the posts funny, others not, but I don't see the harm in it? (unless they said something properly inappropriate like racism/sexism etc that I don't know about)

the triple J social media presence has felt a bit immature for a couple years now to be honest. i've seen them reply to people with shit like "the door's that way -> byeee " when the person's posted a negative comment. often this is in the comments of some trash buzzfeed-level article by them, which has a pitiful amount of likes and 100% negative comments. maybe instead of making salty replies they should realise maybe they're a bit out of touch? maybe change the way they write or what they write about? if you make a post to 1.3 million followers, and it gets barely 200 likes and not a single positive comment, you're probably doing something wrong
