I was in a discussion akin to this on the werelist recently. There, they'd been called "fourth wave" therians. I had a bit to say on the topic, and I still do. Below is my original reply from the werelist, edited a bit for clarity.
Quote: In all the conversations around the state of the community, I feel that we are forgetting to look at the state of the internet as a whole. When I look at what forms of connection are easily available, it's no wonder that the community has become what it is.
Fourth wave [tiktok] therians exist mostly on youtube, instagram, and tiktok. While nuance and the like can be absent in any form of communication, these platforms simply aren't built for it at all. Short-form content thrives off of quick clicks and rapid swiping. You can post all the introspection on those sites you want, but unless it generates easy ad revenue, it might as well not exist at all. This leads to all the posts and conversations that get shared to be ankle-deep at best, ergo that's what the uninformed and uninitiated make the community out to be. You may have the occasional account that gets attention for sharing real experiences, but it's a rarity. We know that social media is predatory and that children are very susceptible to it. There aren't a ton of stand-alone websites like this anymore because of how pervasive algorithm-based platforms have become.
Short-form content has rotted brains to the point where long-form content such as forums and essays cant hold attention. Then it bleeds over into other platforms like Reddit. I could easily write forever about how this probably has a lot to do with capitalism and anti-intellectualism.
Do people need to be aware of the community they're joining before they join it? Absolutely. Should we encourage positive change? Of course. There are a lot of issues that come with children and other uninformed folks joining the community en mass and there always has been. I just think we should be more aware that the environment and framework that these new communities are forming under are inherently hostile to the nuanced conversations that create good community. Growth should always be encouraged, but sometimes the soil you're planted in is pretty nasty.
I find it shallow and a bit dishonest to blame children for the issues within the new community. Most of the time, they are completely unaware that a much deeper and richer community lurks right under the surface, and tiktoks endless desire for ad revenue and attention isn't going to spur them onto these deeper conversations, it's just going to keep them on the app.
Ultimately, I think the hype will die out in time. The community will adapt, and those who turned out to be "real" will stick around and contribute. Best thing we can do is gently educate and not shame them.
