You are Welcome and Thank you too
Spammers are alway at least 1 or 2 step ahead of us 😔

The below will not cut down on Spam e-mails nor will it eliminate Spam e-mails.
Though, it may present some insights as to how exposed your e-mail address may be to Bad Actor Spammers.
E-mail addresses are Bought and Sold on the internet for various reasons including Sold to Spammers.
That is how they make their money.
I have done some testing on some personal e-mail addresses as well as on family members e-mail addresses
Was floored by the results.
Some were exposed by Data Breaches from some will Known Software Developers and even from my Own ISP.
You can only mitigate your exposure in the future and deal wth this Spam as an “ After to Fact “ situation
