Lol. I was laughing because he's the joke. But I don't blame you for not getting that through text. It's all good 👍🏾

Thanks for the laugh bro. You're great!

There are no such signs.

Or even if not, there are 10,000 combos of 0-9 for a 4 digits code like the last 4 of your SSN where if they already have the last digit, the number of combos for just a 3 digit code drops to 1000 if they were to try to brute force it. Significantly easier. Not sure that's what they were going for exactly, but it's a possibility.
