What kind of proof you got? Pic or vid? You can upload a picture to imgur.com or any photosharing site, video to youtube or other video-sharing sites.
Proof is vital because i doubt any action will be taken unless some kind of proof is given.

OBS Studio is an open-source capturing software (for recording gameplay) and it is free, if you want to help out Rising, keep the program open until you see hackers and then start recording.
