Can the admin screen photo contests posted in this forum? I suggest that if the contest involves Facebook with conditions "winner/s will be determine with the most number of likes" be subjected to your approval, if cannot totally ban them. Reason is because this is not proper way to determine the winning photographs based on the essence of every competition. Facebook is a social networking site and not photograpy expert network - unless someone starts doing an account with photo experts in Facebook. A find it disgraceful to the true meaning of competition.
