Why are there too many posers?

There are several reasons why people feign their profiles

1. They feel inferior
• Because they only see their weaknesses while admiring the strengths of others. They are not photogenic, so they can't publicly post their pics, so they use that of others.
  
2. They want to play around
• Some really enjoy fooling others. They love it when some hot blooded profiles comment on their pics like "add me!" "you're pretty!" "cute!" etc
3. They seek revenge
• They pose as their enemies, and make them appear funny, stupid, or promiscous
4. They want anonimity
• This is a rare case, but this is possible.
