Invites back to League of Legends?

Hello everyone!

I played on one league of legends account for years but after a couple of fits of anger at a bad time in my life, the account was banned permanently. Rightly so probably, I'm not here to contest that. However, I got an email from Riot inviting me to come back to play the game on that account...for some reason. Even though I am of course, still banned on that account.

Any chance Riot could NOT do this? I served my punishment and have been playing on another account now for almost two years without issue. I don't need the temptation of thinking I could get back all the skins and money I put into my old account, lol.

Just a little gripe I thought I would mention! Happy Saturday to you all.
