Earning Coins & Giving Appropriate Credit - Community Etiquette
In general spamming existing posts to earn coins will be unwelcome and may result in a forum ban.
Please do use the like, dislike, agree, disagree, funny, winner, informative and the other options for an existing post as an abbreviation of a compliment or view, not an emoticon by itself in a separate reply.
Generally an emoticon or image only post is only acceptable when it truly captures the moment and in those cases it is usually a custom image that someone has deliberately gone looking for to achieve that end. It is like telling a good joke, it has to be well timed and appropriate to the flow of the thread. Here is an example where the thread is about speed controlled fans: http://www.xsimulator.net/community/threads/speed-controlled-fan-dirt-3.6137/#post-67199
