Each response is based on my estimates:

1st question - The contributions and comments naturally disappear when your account is disabled

2nd question - If you’re an admin anywhere, an option is selected that would block users who used the same address as you

3rd question - Special:Contact can be used to disable a wiki (if it’s non-spam), if it’s discovered / estimated that the wiki(s) have a spam purpose to them, The VSTF would probably be the best option.
