Why would someone have the name trapezoid? Oh, because you can sell it for 100$. No, sorry, but i don't think it's a really good idea to have the filter modified as there will be again bypasses and people would most likely more insult than put creative names.
Why did people signed up with that email in the first place?
You didn't tell that accounts (for example Garen) were hacked but their email is invalid and you can't migrate it to later sell it for 15$?
How did people who actually owned these accounts suddenly came back after 8 years and knew exactly which password and email they put, even though it was a invalid one?
