Too much text in TextArea causing form to spam out

Hi, I’m in a bit of a pickle and can’t find anything online. I’ve created a form for people to submit essays through contact form 7. When they put their essay in the textarea it’s causing the form to be marked as spam. Here is the link to one of the forms: https://cancerpathways.org/education/writing-contests/2nd-annual-alaska-teen-writing-contest/

I have put in max fields of over a million!!!

When you put in a lot of text it gives me the orange border of death! Please help! The site is live and I don’t know what to do!

Here is the code:
