I don't have a specific post, but the wife of a friend has a 1 year old she vicariously lives through by putting her through pageants.
One day she had entered into a contest on Facebook. Whoever had the most "likes" by a certain time won something trivial like a free hairbow or something stupid.
Anyway, throughout the day she constantly posts things like "Only 5 hours to go, we are just 3 behind" "Please vote for my daughter!" Several people get private messages from her to beg for a vote.
I get fed up half way through the day and pull my like from her daughter and give it to the other person. The daughter of this crazied mom ended up losing by 2. Whoops on me.
Within hours a losing she makes a post that looks like "Thanks to all my FRIENDS that helped us out."
Apparently this pisses some people off and she posts the next morning how sorry she is for causing drama.
Needless to say, I ended up blocking about 4-5 people after this. Drama over a pageant? Wow.
