Hi, I'm sorry you don't like the limitation :( this is for short thoughts you want to share, not really huge conversations, there are better places for that IMO.
I use Mastodon which has a 500 limit, and even that sometimes is not enough.
Also open source.
Saying shitty/toxic stuff can be done concisely. Giving a nuanced response is simply not possible. So people respond with jokes/sarcasm/counter toxic stuff. And the cycle continues.
