This is an extremely stupid idea. Just do a recursive DNS query down to the root domain. Whoever the fuck believes that Wikipedia is an immutable, perfect, godlike accurate website, deserves the malware and abusive redirects this Wikipedia DNS will inevitably provide.
If you read the readme, this looks like it’s specifically for when you don’t know the correct tld or spelling of the site you’re looking for. Google searches often censor sites of borderline legality, but they’ll usually still have Wikipedia articles with accurate links.
This specifically only redirects .idk domains as a search helper. Could it possibly work better as a browser extension? Maybe. :)
The literal entire point of recursive DNS queries and the safety algorithms behind it allow for a qualified top-level domain to be discovered while reducing risk of DNS poisoning.
This tool is the equivalent of someone telling you to remove and replace your front door lock with a wild parrot.
