I have been experiencing the same thing for over a month now. I was permanently suspended for the usage of third party applications. Through various tickets, I was given the usual copy and paste reply and some of them just straight up sent me the scripting copy pasta. The only way I could have gotten suspended is through this skin changing program known as SkinPreview but I have not used SkinPreview for a while now. In addition to this, I had used MKjogo in the past but that was like a year ago. It's been wiped out of my pc for a while. I was told that and through various researches that using custom skins that riot does not intend to permanently suspend people for the usage of these custom skins. However, I wasn't brought to light yet and I really want my account back. :( I had dedicated so much time into it, every champion, many skins.. I've seen some get unbanned from these forums from posting so this is my plea.
