It's not about Karma and points, it's about the quality of the site as defined by the current users. You weren't downvoted for trolling, but for the style of your comment. LOLspeak and emoticons are standard elsewhere, but not here.
Generally, your 'thanks' will be better appreciated here if you use the best standard English that you know. You aren't being punished, rather your comment was being moved lower on the page to make room for better ones. You can choose to ignore the feedback this rearrangement provides, but your stay here may be more enjoyable if you pay some attention to the local customs.
