farming for likes is just wrong

It's just another way of showing that you've actually read the post and followed all of the requirements, you dont really gain anything from having likes so 'farming' for them doesnt really matter.
Plus in regards to your other post on the other giveaway about not having a Twitter or Instagram account, you can always just make one. They take a few seconds to make and it's just another way of showing support.
