Probably voiding warranty for any phone that has its battery replaced by the user instead of having it done at an apple store/apple vertified store. Or some good old planned obsolescence where the phone detects a replacement battery and just stops working as fast as it used to. Anything to get people to buy the next new iphone every year.
I find it especially concerning that subreddits dedicated to mental health like r/Anxietyhelp or r/therapy are just thrown into the mix to have some randoms be mods. They could easily come with bad intentions and even well intentioned individuals could inadvertently cause a lot of harm.The job of managing any community dedicated to helping those suffering from mental health issues is by no means an easy task just anyone can do. A lot of knowledge about mental health and certain subtle/not easily recognizable problems (i.e. covert incitement of suicide) is required. This is not something any responsible admin would just give away to just about anyone like this.
