Only site mods can ban players from the website, but that's way too severe a punishment for just faking a speedrun. If you want to ban a player from the community, just reject all of their runs, and don't accept any runs they submit in the future.

No its not lol, it says in site rules that "Splicing and/or faking/falsifying runs for any reason" is a bannable offence.

Most large games give runners second chances before they get banned from the community, and in my opinion that's fine as long as the perpetrator doesn't do it again. That is just my opinion though, I know that faking runs is a bannable offense.
