Blacklisted Domains

The blacklist can only be updated by myself (@409H) and MyEtherWallet (@tayvano). This is a to prevent anyone from modifying the blacklist (ie: removing something). To request a change to the blacklist, please open an issue or open a pull request with the changes. Make sure you give some details on why the changes are needed.

Whitelisted Domains

The whitelist can only be updated by myself (@409H) and MyCrypto (@tayvano). The whitelist will prevent any false-positives from happening with the Levenshtein algo (special thanks to @sogoiii). If you find a domain that is wrongly blacklisted, then please open an issue or open a pull request with the changes.
