You has an account banned, you can always create another one...
Tyler1 did not get any of his accounts back, the dude had an ID-ban which means any new account he was spotted playing on was permaban, he wasn't able to create new accounts anymore.
Get the difference ?
ID bans are different—and more serious—than normal account permabans. An ID ban is a rare, drastic step we take against players who've consistently chosen not to play to win or to abide by our terms of service. When we determine a player should receive an ID ban, it's effectively a statement that we don't want that particular person to create, access, or use any account on a Riot platform or game for the duration of the ban.
