Today, I got a message from System saying the following:

"Attention! **** Your solution 247902293 for the problem 1923A significantly coincides with solutions Wasif_Shahzad/247902293, Ruk_NemJki/247976061. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.me/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked."

I don't know where to appeal but I've gotten proof against this message. MikeMirzayanov Here are my IDE cache files in a zip file. Link.

I know screenshot will be kinda useless but here's that as well:

I hope that appropriate action is taken and I'm proved innocent out of it. I repeat I don't know where to appeal so that's why I'm writing this BLOG. If anyone knows the correct place to appeal then please tell me in dm or comments. It would be highly appreciated.
