Codearena Bugs and Suggestions

I found some bugs in Codearena that could let user cheat by uploading code to ace-editor during fight . This makes fight unfair and other opponent will loose motivation to fight as ,I can win the fight in less than a minute.

How I did !

I tried these several times on different accounts and all are still active beacause I choose other user's random solution from other editorial account . I managed Plagirism :-P

• I made class file-upload visible by making class file-upload visible!
• This lets me upload regular code just like normal ace code editor
• And , Apart from this , class ace_constant ace_other can be tampered to push code into the ace editor
• I was able to manupulate the time-counter on codearena by blocking XHR Request on jstimezonedetect Script.

Demo

I also tried adding code to the Editor's native source

Similarly i tried many times

I think adding a HE-Biased Chatbot on page will be more beneficial for everyone!

Note:

• Inviting preferred opponent via Bot. Could invite via a unique Token via Bot
• Invite FB Friends directly . That's a Jackpot. More Traffic.
• Could answer Basic Queries and problems regarding Editor as well

I have more ideas and features , on how Hackathons can be made more awesome through HE Platfrom. I have attended more than 5 hackathons from HE , and felt need for some changes . :-)
