Why do you need to use a minimum of 15 characters to answer a question?

It is fighting robots answering. Not only can they NOT MAKE OUT THE PHOTOS, they also cannot read numbers. So saying 15 messes them up too...and you are giving a more fuller answer to the question which benefits the asker.

I only know a few shady characters but it must be the pedantic police who enforce literary law.

You guessed it, Frank Stallone.

errmmm (15 characters)

I suppose to was to stop the spammers and point gamers.

a lot of people were point gaming by just typing. asdez, or just a bunch of random letters.

so now ya have to type at least 15 random letters......

or type asdez........................... with the extra dots.

Safety feature to make sure an adequate answer is given

YA people thought it would prevent so much Trolling , but it does not really

cause you wont be able to answer the question if you dont

to stop spam, trolls and point gaming

Because too many people were answering questions with random letters like "asdf" or "ook."
