Being an active member of the Ethereum Stack Exchange community, I stumble upon many threads started by new users containing sensitive information about their digital wallets - private keys and 12-words mnemonics.
Here's just two examples I found in my recent revision history:
- How to generate account address from pivate key?
- Unknown account error while deploying dapp on Ropsten testnet
The community always react quickly to remove the private information from the question description, but it's still available in the revision history. Although most likely those private keys map to empty wallets used for development, you can never know.
- Is there a way for the community moderators to completely erase this type of information from the revision history?
- To prevent future mistakes, is there a way for the question editors in Bitcoin, Ethereum etc to show a warning whenever a 64-char word is typed? That it, something like "Heads up! You might've pasted your private key. It's not safe to do that, just use a placeholder". Unfortunately, it might be harder to validate against 12-word passphrases, there could just be a warning whenever the word "mnemonic" or "passphrase" shows up.
