Yes, there is a (small) risk. EA does not support third-party extensions. However, we have over 3000 active users and permanent account bans are extremely rare. If you only use Futinator and no other tools/apps and do not transfer coins and make captchas wrong, your risk of ban is extremely low. We have users since Fifa 19 who never had a ban. It's up to you how responsibly you use Futinator. The worst thing that can normally happen to you is a soft ban for a few hours or verifcations (which can happen even if you are not using Futinator).
