Are there any EA reps we can contact through this forum? I discovered a game ruining glitch.

I discovered a FG block glitch that is unstoppable and easy to do. No not that timing thing, that isn't a glitch btw (you should mix up your timing).

I discovered a disconnect glitch years ago and on the reddit forum i contacted a rep and was rewarded with a lot of coins and any cards i wanted. Do they still do this?

This would pretty much ruin the game and honestly don't know how they could implement code to stop it.

EA doesn't do that anymore and you can't speak with them directly here (or anywhere else for that matter). You can open a ticket and report it at help.ea.com. You are also welcome to DM me, and I can share it in my chat with them.
