Can Students Copy/Paste in Respondus?

I use Respondus for some exercises in my online classes merely to prevent students from copying and pasting. With time adjusted appropriately, it introduces some friction into successfully to bypass the learning process.

Some students just copy the AI answers, which tells me I need to adjust the time allowance. I have noticed however that sometime student responses will include texts with odd or changing fonts. I know that it is possible to make these changes in the text entry box, but that seems like something most students would be unlikely to do. I also only notice this in cases that also appear to be AI-generated text. Have they found a way to allow copying and pasting in Respondus?
