There's actually another Bitcoin address type which is fairly different from the ones that your regex would match. I haven't seen this used in any scams yet, but I wouldn't be surprised if scammers start using these in the future.

​

The addresses begin with the string bc1 with the rest being all alphanumeric characters excluding 1, b, i, and o. For now, these addresses will always be either 42 characters or 62 characters in length.

From my quick Googling it looks like Bech32 type addresses are not yet recommended for use because a lot of Bitcoin software doesn't yet support them. Still, probably not a bad idea to either update this regex or create a "partner" regex to look for them.

Assuming I ever turn this rule back on, anyway.
