Swipe text censoring

So I've noticed for a while now that the ios keyboard has lots of problems for me. I used to be a boss at swipe texting, but now it's a nightmare. For one, it seems to refuse to let me swipe things that could be considered "triggering" or whatever. For instance, I can never get "murder" or "suicide" to get recognized. It'll suggest anything but that. Or things that are sexual in nature, like "penis" for example.

Secondly, I feel like the accuracy has gone down quite a bit in general. Like sometimes I'll have to swipe a word so many times that I'd be done typing it had I just hunt and pecked my way through it.

I feel like this has been going on for at least a couple years now and I've replaced my phone in that time so I know it's gotta be a software issue. Or PEBCAK, but I don't really see why that would have suddenly changed. Anyone know how I can fix any of these problems?
