Yes, there is a way to turn off these subscriptions. Go to your Settings (top right) > left side, under My Account - select General Settings > under Messaging & Notification > Default Thread Subscription mode: change this to Do not subscribe. See screenshot below:
On the other hand, if you DO want to receive notifications on threads that you subscribe to, you would come to the same place here but change that setting to whichever option in that drop down menu on how frequently you'd like to receive notifications.
Let us know if that works for you and/or if you need further assistance. Thanks!
