Wrongly accused for MMR boosting and not sure what the "reason" is

Got an email this morning (11/21/2015) from riot stating something about MMR boosting and account banning, I thought it was a generic post to all players about warnings on MMR boosters. I was shocked that was actually targeting my account on NA server. I played as shootokilla for 3 seasons now, in season 5 I've picked up Wukong and did many games with him. Always played on my own account and did not share it with anyone else. This is just flat out rude to ban players for 2 weeks for nothing they did wrong.
