Recent banwave.

Send in a ticket to player support (scroll up and click the "support" tab) and explain that the only thing you used is cursevoice. If that's what flagged your ban then it'd be a false positive and they'd overturn it. The first reply you'll get will probably be copy-pasta (It's like the sorting hat), but once you respond to that one they'll assign you to a human who'll deal with you one on one.

Stop telling us to go to support. They're just useless. It's the same "You cheated, we can't say why because hurr integrity. Gtfo"

MKJogo?

You can contact Support if you are sure that it's a mistake.

I got banned for Snop Doggin. Rito hates snoop cuz they racist.

I've contacted support twice, once asking to fix the problem(that lead me to be "transferred to Player Behavior Specialist", but that was two days ago) and then asking if any of the programs(curse,replay.gg) I used would trigger a ban and that lead to the auto message "Your account has been permanently suspended following the use of scripts, hacks, exploits or unauthorized third-party programs in League of Legends." Support is being no help because it's all canned response. The only hope for our accounts is to get enough attention on the boards so a rioter can look into it.

No way bro, they never remove 3rd party bans, check my post, thats shitttt, i didnt even use cursevoice. I still don't know why i got banned. http://boards.na.leagueoflegends.com/en/c/player-behavior-moderation/6uz47BtM-thats-how-riot-game-support-reply-me

They don't really overturn bans if you're not famous and streaming (since then you have proof and it'd look really bad), but you can keep ticketing indefinitely (they literally can't stop you).

Ironically, the closest thing you can do to repaying in kind is to set up a script (lol) to reopen tickets about it forever, since they'll never move on the matter.
