A lot of modern social media systems have adopted ways to engage with users by providing a means of rating, retweeting, liking, starring etc etc. This platform also has this functionality in the form of 'likes/thanks' with the thumbs up button. A lot of users are used to seeing this kind of thing elsewhere but more traditional forum users do not see the need for such a thing.
If the like/thanks functionality may not be your cup of tea, you do have the option to completely disable it from your experience on the community to better suit your personal preferences. If you wish to remove the button from your view, follow these steps to disable it:
Go to your user settings page
Put a tick in the box for 'Hide Thanks buttons and counts'
