Important
Official Riot Games response. We are glad that you enjoy our game so much and you are trying to make a program that makes peoples playing time easier! While we don’t strictly condemn the use of third-party modifications, these programs can be dangerous and worthy of suspension where they violate our Terms of Use. I can’t tell you whether a particular third-party modification is against our Terms of Use or not, but you can follow these general guidelines: We identify and suspend accounts for using third-party programs intended to offer a competitive advantage by affecting gameplay in any way We cannot control what a third-party developer makes or changes, so a program that was once acceptable may have versions which violate the Terms of Use Some third-party developers may not have your best interests in mind, so please be aware that these types of files can contain keyloggers, viruses, and malware. Third-party modifications may affect your game in unexpected ways, so if you’re having technical issues, try uninstalling these programs before doing anything else. Regarding one point you mentioned: 'Profile Customization – client‑side changes to profile icon, background, status message, and challenge badges (visual changes on the client side only).' if you mean custom customization that is not official, then this is definitely not allowed In general, if you find a third-party modification suspicious, it’s best to avoid using it. I hope this clears things up a bit, but if you have any other questions, please let me know. Alinas, Riot Games Player Support IT IS NOT BANABLE
