Riddle voting & auto removal system

[cedricium]

After showing riddler to the peeps at work, we quickly found out that some of the riddles are too hard or too ambiguous and thus having a system in place to vote whether a riddle was good or not would be helpful.

Basic implementation might go as follows (assuming riddles are moved to a database):

• riddle sent to user, after they reveal the answer, another attachment added with 2 buttons: 👍 and 👎 or similar
• user can then click either button to cast their vote - only 1 vote per user for each riddle
• knowing the number of votes per riddle and upvote:downvote ratio, can then remove a riddle that falls below a certain threshold
