So yesterday, my friend lost his account to a phishing scammer because of stupidity. Basically, one of his friends sent a message saying "Riot Games gives a Mystery Skin for free to every player, enter this link for more information:" with a link that I presume allows the scammer access to the persons account. After my friend clicked on it, nothing happened until today where his account sent everyone on his friends list the same message, including mine. My friend did not write anything and even said he did not log in today.
Guys beware. If someone sends you that message + a link, DO NOT CLICK ON IT! Your account could be hacked.
